Abstract

Thermogravimetry, derivative thermogravimetry and infrared spectra have been applied to the investigation of the thermal behaviour and spectral properties of the dimeric complexes Cu2(2-Clbz)4(denia)2(I), Cu2(2-Brbz)4(denia)2(II) and Cu2(3-Brbz)4(denia)2(III), where 2-Clbz, 2-Brbz and 3-Brbz = 2-chloro, 2-bromo- and 3-bromobenzoate anions, denia = N,N-diethylenicotinamide. Thermal decompositions of all studied compounds proceed in two steps. The final product of thermal decomposition is CuO. The thermal stability of the complexes can be ordered in the sequence I < II < III.
