Some studies in inorganic complexes. XXVI. Complexes of 6-Methyl-2-thioamidopyridine

Abstract

Several complexes of the chelating ligand 6-methyl-2-thioamidopyridine have been prepared end studied. Infrared spectra indicate that the sulphur atom of the thioamido group is bonding in the complexes: [CoL₂(H₂O)₂][ClO₄]₂, [NiL₂Br₂], [CuL₂]I, [Ru₂L₄Cl₂O]Cl₂, [OsL₂Cl₂], [AuL][AuCl₁], and [HgLI₂] whereas nitrogen bonding occurs with [FeLCl₃]₂, [ZnL₃][ClO₄]₂, [SnLI₄], and the deprotonated species [In(L-H)₃]. Copper(II) was reduced to copper(I), e.g. [CuL₂][CuBr₂]. Studies in the visible spectrum, magnetic measurements, and conductances in both nitrobenzene and dimethylformamide were also made.
