Abstract: | Complexes of CoII, NiII and CuII with 3-substituted-4-salicylideneamino-5-mercapto-1,2,4-triazole have been prepared and characterized by elemental analysis, electronic, i.r., e.s.r. and t.g. studies. T.g. studies show that the complexes thermally degrade in two steps. Kinetic and thermodynamic parameters were computed from the thermal decomposition data. The activation energies of both the thermal degradation steps lie in the 0.24–42.67 kJ mol−1 range. This revised version was published online in June 2006 with corrections to the Cover Date. |
