N2  - The crystal and molecular structures of three new nickel complexes are presented: diaqua (4,4&acute;-dimethylbipyridine- N,N&acute;)(methanol) thiosulfato(S) nickel(II) (1), aqua terpyridine(N,N&acute;,N&acute;&acute;) thiosulfato(S,O) nickel(II) hemihydrate (2) and bis(dipyridylamine) thiosulfato(S,O) nickel(II) hemihydrate (3). Compound (1) is triclinic, P 1&#8211;, a 8.1570(16), b 9.6847(19), c 11.714(2) &#197;, &#945; 76.73(3), &#946; 73.56(3), &#947; 78.23(3)&#x02DA;, V854.2(3) &#197;3, Z 2, conventional R (onF) being 0.034 for 5515 No observed reflections (I &#62; 2&#963;(I)). Compound (2) is monoclinic,C2/c, a 27.866(6), b 9.2743(19), c 14.216(3) &#197;, &#946; 114.24(3)&#x02DA;, V 3350.1(12) &#197;3, Z 8, R 0.034, No 5690. Compound (3) is orthorhombic, Iba2,a  12.9860(10),b 16.8210(10), c 19.4790(10) &#197;, V 4254.9(5) &#197;3, Z 8, R 0.038, No 3956. The three compounds are monomeric, with the nickel ion in a distorted octahedral coordination. In compound (1) the thiosulfate anion binds through sulfur as a monodentate ligand, while in the other two it behaves as a chelate, binding through oxygen and sulfur. The strong hydrogen-bonding interactions involving the aqua ligands and the water solvate molecules define chains with a strong internal connectivity and which are loosely linked to each other via much softer C&#8211;H&hellip;O interactions.
