Binary complexes of the type [M(S2CCN)(2)] (M = Mn2+, Fe2+, Co2+, Ni2+, Cu2+ and Zn2+) have been synthesised from alcoholic solutions. They have been characterised using elemental analyses, IR, UV-VIS spectroscopy, magnetic susceptibility measurement and solution conductance data. In thermogravimetry (TG) studies, all these complexes exhibit a prominent weight loss step between 100 and 330 degreesC under a N-2 atmosphere. Besides, a second weight loss step has also been observed beyond 800 degreesC for the Mn2+, Fe2+ and Co2+ complexes, between 400 and 600 degreesC for Zn2+ complex and beyond 380 degreesC for Cu2+ complex. Broad differential thermal analysis (DTA) endotherms are observed corresponding to these weight loss steps. The first weight loss in the TG scan of the complexes follows a deceleratiory alpha-time curve with D-3 mechanism for all complexes. The activation energy (E-a) for the thermal decomposition varies between 43 and 115 kJ/mol and removal of CS2 and/or CS have been suggested. Various decomposition parameters have been calculated.
