New mixed-ligand complexes of the following stoichiometric formulae: Ni(2-bpy)2- (CBr2HCOO)2.5H2O, Ni(4-bpy)2(CBrH2COO)2.2H2O, Ni(4-bpy)2(CBr2HCOO)2 .2H2O, Ni(2,4'-bpy)2(CBr2HCOO)2 .4H2O, Zn(2-bpy)(CBrH2COO)2 .H2O and Zn(4-bpy)(CBr2HCOO)2.H2O (where: 2,2'-bipyridine = 2-bpy, 4,4'-bipyridine = 4-bpy and 2,4'-bipyridine = 2,4'-bpy) were isolated in pure state. The IR and VIS spectra, molar conductivity, magnetic moments are discussed. Thermal behaviours of complexes were studied by means of DTA, DTG, TG techniques under static air conditions. During heating the complexes decompose via different intermediate products. The final product of nickel(II) complexes pyrolysis was NiO; in the case of zinc(II) complexes total mass loss was observed.
