Pyridine adduct complexes of 4-Salicylaldimino-2,5-dimercapto-1,2,4-triazole (H2Saldmt) of compositions PyH[Ni(Saldmt)Py] and [Ni(Saldmt)H2O)]were prepared and characterized by elementalanalysisand spectral studies. The TGAandDTAanalysiswere performed between temperature ranges 40-650°C. The complexeswere diamagnetic and possess four coordinated square planer structure. The IR spectra suggested coordination of ligand bydeprotonation of thiol (-SH) and phenolic (-OH) as tridentate (O, N and S)donor molecule. The TG shows multistep decomposition of complexes with exothermic DTA maxima.
