Abstract
Complexes [SnCl3(HBs)] (I) and [SnCl3(Is2H)] · nSolv (n = 2, Solv = CH3CN (II); n = 0 (III); n = 2, Solv = DMF (IV)) with the molar ratio Sn: ligand = 1: 1 are prepared by reacting SnCl4 with salicylic aldehyde benzoyl or isonicotinoyl hydrazone (H2Bs or H2Is). IR and 1H NMR spectroscopy proves that the ligands in I–IV are coordinated in a tridentate-cyclic mode through the azomethine nitrogen atom and the oxygen atoms of the oxy group (in I–IV) and the carbonyl (I) or oxyazine group (II–IV), so that the ligands in II–IV are in the N(py) protonated form. The thermal decomposition of complexes is found to be accompanied with the elimination of chlorine- and tin-containing species into vapor phase. The molecular and crystal structures of complexes I and II are determined by X-ray crystallography.
