Abstract

The reaction of SnCl4 with 2-hydroxybenz(2-hydroxynaphth)aldehyde nicotinoylhydrazones (H2Ns, H2Nnf) in CH3OH gave non-electrolyte complexes [SnCl3(HNs)] (I) and [SnCl3(HNnf)] (II), which were recrystallized to give the solvates [SnCl3(HNs)] · DMF (III) and [SnCl3(HNnf)] · 2DMF (IV). It was found by IR spectroscopy that the ligands in I–IV are protonated at the N(Py) and coordinated in the tridentate chelating mode through the azomethine nitrogen atom and oxy and oxyazine oxygen atoms. The thermolysis of I–IV and electron impact-induced fragmentation of I and II are accompanied by the formation of the complexes [SnCl2(Ns)] and [SnCl2(Nnf)]. The molecular and crystal structures of IV were determined by X-ray diffraction (CIF file CCDC no. 816105).
