Summary

[NiL2X2] (L =N,N′-dimethyl-1,2-ethanediamine; X = Cl, CF3CO 2 , CC13CO 2 and CBr3CO 2 ), [NiL2C2O4] · H2O and [NiL2X2] · 2 H2O (X = Br, 0.5 SO 4 2− and 0.5 SeO 4 ) have been synthesised and their thermal studies carried out. Thermally induced phase transition phenomena are noticed in [NiL2X2] (X = CF3CO 2 and CCl3CO 2 ) and their probable mechanisms are described. [NiL2X2] (X = Br, 0.5 SO 4 2− and 0.5 SeO 4 2− ) and [NiLX2] (X = Cl, 0.5 C2O 4 2− and 0.5 SO 4 2− ) have been prepared by solid state pyrolysis from the respective parent diamine complexes. [NiL2X2] have been made in solid state by temperature arrest technique from [NiL2(CX3CO2)2] (X = Cl and Br).
