Synthesis,characterization and thermal studies of some new organotin(IV)complexes with aniline N-thiohydrazide and benzaldehyde aniline N-thiohydrazone

摘要

The complexes of parachlorotribenzyltin (IV)chloride and parachlorodibenzyl tin (IV)dichloride with aniline N-thiohydrazide (L~1),and benzaldehyde aniien N-thiohydrazone (L~2)have been synthesized.The complexes have been characterized by elemental analysis and spectral (UV-VIS,IR&NMR)studies.Ligand in the complex acts as bidentate nd coordination takes place through sulphur and terminal nitrogen.These are 1:1 metal ligand complexes.Various thermodynamic parameters have been calculated for the decomposition steps using TG-DTA curves.Activity fo all the complexes Vs.Rhizoctonia bataticola fungal strain have been studied and the general order of activity have been deduced.
