CH16438Interpenetrated Double Pillared-Layer CoII MOFs with pcu Topology

In-Hyeok Park, Yunji Kang, Eunji Lee, Anjana Chanthapally, Shim Sung Lee and Jagadese J. Vittal
pp. 461-467
Graphical Abstract Image

The influence of organic backbone on the bonding modes of the dicarboxylates, conformations of the of the long and flexible dipyridyl ligand, and pore size in isoreticular metal–organic frameworks formed by three double pillared-layer CoII metal–organic frameworks with a pcu topology is discussed.

Graphical Abstract Image

1-(4,2′:6′,4″-Terpyridin-4′-yl)ferrocene offers a fixed V-shaped N,N″-donor set, but this does not lead to a predictable assembly algorithm; polymer and metalloamacrocycle formations compete. Similar competitive behaviour is observed in coordination assemblies based on 1-(4,2′:6′,4″-terpyridin-4′-yl)ferrocene, with the greater conformational flexibility of the latter adding to the non-predictability of the assembly process.

CH16547Synthesis and Structures of Rare Earth 3-(4′-Methylbenzoyl)-propanoate Complexes – New Corrosion Inhibitors

Caspar N. de Bruin-Dickason, Glen. B. Deacon, Craig M. Forsyth, Schirin Hanf, Oliver B. Heilmann, Bruce R. W. Hinton, Peter C. Junk, Anthony E. Somers, Yu Qing Tan and David R. Turner
pp. 478-484
Graphical Abstract Image

A series of rare earth (RE) 3-(4′-methylbenzoyl)propanoate (mbp) complexes [RE(mbp)3(H2O)] (RE = Y, La, Ce, Nd, Ho, Er) have been prepared by either metathesis reactions between the corresponding rare earth chloride and Na(mbp) or protolysis of rare earth acetates by the free acid.

Graphical Abstract Image

Structures of [Co(NH3)6][Ln(dipic)3] hydrates have been analysed in terms of the weak interactions occurring between the achiral cation and the chiral anions.

Graphical Abstract Image

Cobalt(ii) complexes with terpyridine-type ligands, [Co(n-pyterpy)2](ClO4)2 (n = 3 (1), 4 (2)), show different molecular assemblies depending on the nitrogen position in the pyridine substituent. The cooperativity estimated from the magnetic behaviour reflects their assembly nature.

CH16492Evaluation of Methanol Induced Free Radicals in Mice Liver

Lifang Zhou, Hongli Zhao, Tieying Pan, Adrian Trinchi, Minbo Lan and Gang Wei
pp. 499-504
Graphical Abstract Image

In this work, oxidative stress (OS) models of methanol in mice were successfully established. The experimental results clearly demonstrated that methanol could stimulate the production of hydroxyl radicals in the liver of mice to induce OS. Rhubarb and vitamin C were found to have a protective effect on the liver of mice under acute OS.

CH16614Synthetic Models for Nickel–Iron Hydrogenase Featuring Redox-Active Ligands

David Schilter, Danielle L. Gray, Amy L. Fuller and Thomas B. Rauchfuss
pp. 505-515
Graphical Abstract Image

Nickel–iron hydrogenases produce and consume hydrogen using elaborate electron and proton transport machinery. Although synthetic modelling of nickel–iron hydrogenases has developed rapidly, it has largely ignored aspects of substrate transfer. Reported here are nickel–iron mimics bearing redox-active ferrocenyl ligands, these trinuclear systems representing advanced models of the native enyzmes.

CH16648Transition Metal Thiocyanate Complexes of Picolylcyanoacetamides

Yuniar P. Prananto, Aron Urbatsch, Boujemaa Moubaraki, Keith S. Murray, David R. Turner, Glen B. Deacon and Stuart R. Batten
pp. 516-528
Graphical Abstract Image

The transition metal complexes of picolylcyanoacetamides with thiocyanate are presented. Discrete tetrahedral, octahedral, and polymeric structures were isolated, and for cobalt(ii) complexes the magnetic susceptibility was measured.

CH16565Weak Intermolecular Forces, but High Melting Points

Jiabin Gao, Djamal Djaidi, Christopher E. Marjo, Mohan M. Bhadbhade, Alison T. Ung and Roger Bishop
pp. 538-545
Graphical Abstract Image

Racemic 4 melts above 350°C despite its low molar mass and absence of Pauling hydrogen bonding. X-Ray and Hirshfeld surface analyses reveal excellent complementarity between homochiral molecules of 4, and layers of opposite handedness are linked by the aza-1,3-peri hydrogen interaction. Weak intermolecular forces are discussed in context of the Lipinski ‘rule of 5’ solubility criteria.

CH16555In Situ Spectroelectrochemical Investigations of RuII Complexes with Bispyrazolyl Methane Triarylamine Ligands

Carol Hua, Brendan F. Abrahams, Floriana Tuna, David Collison and Deanna M. D'Alessandro
pp. 546-555
Graphical Abstract Image

Two new triarylamine-based ligands containing the bispyrazolylmethane moiety and their RuII terpyridine complexes exhibit interesting electrochemical and spectroscopic properties. In particular, formation of the triarylamine radical cation leads to an electrochemically induced dimerization process.

CH16663Engineering Isoreticular 2D Metal–Organic Frameworks with Inherent Structural Flexibility

Alexandre Burgun, Witold M. Bloch, Christian J. Doonan and Christopher J. Sumby
pp. 566-575
Graphical Abstract Image

The chemical mutability of metal–organic frameworks (MOFs) is an advantageous feature that allows fine-tuning of their physical and chemical properties. Herein, we report the successful isoreticulation of a MOF by modifying the steric bulk and length of the original ligand separately and in combination.

CH16678Syntheses and Structure Investigations of 3d Transition Metal Complexes with a Flexible N4O2-Donor Hexadentate Schiff-Base Ligand

Kyle J. Howard-Smith, Alexander R. Craze, Mohan Badbhade, Christopher E. Marjo, Timothy D. Murphy, Patrice Castignolles, Richard Wuhrer and Feng Li
pp. 581-587
Graphical Abstract Image

The syntheses and structure investigations of four new 3d transition metal complexes with a flexible N4O2-donor hexadentate Schiff-base ligand are described. The molecular structures of the FeIII, CoIII, and NiII mononuclear complexes demonstrate distorted octahedral coordination geometry. The CuII complex shows a trinuclear structure.

Joshua J. Brown, Aidan J. Brock, Michael C. Pfrunder, Julia P. Sarju, Abigail Z. Perry, Adrian C. Whitwood, Duncan W. Bruce, John C. McMurtrie and Jack K. Clegg
pp. 594-600
Graphical Abstract Image

The co-crystallisation of the linear halogen-bond donor 1,4-DITFB with three symmetric dipyridylacetylacetone isomers produces four different halogen-bonded networks.

Graphical Abstract Image

N,N′-Bis(3-alkoxy-2-hydroxybenzyl)cyclohexane-1.2-diamines (alkoxy = OCH3, OC2H5) form, with zinc acetate and lanthanide nitrate (Ln = Gd, Tb, Er, Yb) in methanol, the isostructural heterodinuclear complexes [Zn(L)(µ-CH3COO)Ln(NO3)2]. In these complexes, zinc(ii) is coordinated by an N2O3 donor set with trigonal bipyramidal geometry, whereas the lanthanides possess an O9 coordination environment in a capped square antiprismatic configuration.

Graphical Abstract Image

Two novel oxovanadium(iv) compounds were synthesised and characterised. Their crystal structures and anticancer activities were studied. Compound 2 was found to have strong anticancer activities towards A549 (human lung carcinoma cell line).

Graphical Abstract Image

The synthesis of DAHA-EDTA is a simple two-step high-yielding process. Its use for Cu-64 radiolabelling of the B72.3 whole antibody was investigated. The biodistribution in LS174t tumour-bearing mice showed high uptake in the tumour and rapid clearance from the blood within 24 h.

CH16586Structure and Magnetic Studies on a Series of Two-Dimensional Iron(II) Framework Materials with Varying Ligand Characteristics

Matthew A. D. Roxburgh, Samantha Zaiter, Xina I. B. Hudson, Benjamin R. Mullaney, John E. Clements, Boujemaa Moubaraki, Keith S. Murray, Suzanne M. Neville and Cameron J. Kepert
pp. 623-631
Graphical Abstract Image

A series of bis-pyridyl linkers are combined with the {Fe(NCS)2} motif to form a family of seven coordination polymer analogues with a stacked (4,4)-grid topology. The resulting FeII coordination environment is well established to give rise to spin crossover behaviour, yet these materials remain in the high-spin state to low temperature. This comparative study provides insight into the critical influence of framework structure on producing spin crossover.

CH16577Crystal Structure of a Heterometallic Luminophore: The RuII Complex of a Ferrocenyl-Terpyridine with a Flexible Linkage

Young Hoon Lee, Jong Won Shin, Yusuke Sekimoto, Shinya Hayami, Jack Harrowfield and Yang Kim
pp. 632-636
Graphical Abstract Image

Crystal structure determination on the mixed ligand complex [Ru(tpy)(L1)](ClO4)2 (tpy = 2,2′:6′,2″-terpyridine; L1 = 4′-(ferrocenylmethylaminomethylphenyl)terpyridine) shows the ferrocenyl group to be located as remotely as possible from the RuII centre. This may explain the fact that emission from the RuII centre is detectable even at room temperature in solution.

Yu-Qing Yao, Qing Liu, Ying Huang, Qian-Jiang Zhu, Yun-Qian Zhang, Xin Xiao, Zhu Tao and Gang Wei
pp. 637-641
Graphical Abstract Image

Two Q[10]-based supramolecular assemblies were prepared via different approaches, and these Q[10]-based supramolecular assemblies possess porous features that suggest that Q[n]-based compounds could be used to manufacture molecular sieves and sensors and applied in absorption and separation technologies
