THE FORMATION, PROPERTIES AND COMPOSITION OF TIN(IV) COMPLEXES WITH 2‑HYDROXYBENZ‑(‑1‑NAPHTH) ALDEHYDES AROYLHYDRAZONES

Abstract

The complexes of composition [SnL2] have been obtained by SnCl4 interaction with 2-hydroxybenz-(-1-naphth)aldehydes benzoyl-(2-hydroxybenzoyl)hydrazones (2-naphthoyl-(3-hydroxy-2-naphthoyl)hydrazones) (Н2L) in aqua-organic and low alkali media (ethanol in the presence of sodium ethylate and methanol with the addition of ammonia solution). It was proved by methods of mass, electronic and IR spectroscopy ligands molecules to be coordinated by tin atom as tridentate ones via azomethine group nitrogen atom and enol and oxy-groups oxygen atoms. The thermal stability of obtained compounds has been studied. The structure schemes are offered.
