New mixed-ligand complexes of the stoichiometric formulae: Mn(4-bpy)2(HCOO)2_2H2O, Co(4-bpy)(HCOO)2_H2O, Ni(4-bpy)(HCOO)2_4H2O, Cu(4-bpy)(HCOO)2_H2O, Zn2(4-bpy)3(HCOO)4 and Cd(4-bpy)(HCOO)2 (where 4-bpy = 4,4_-bipyridine) have been isolated in pure state. The IR and VIS spectra (for compounds of Co(II), Ni(II), Cu(II)), molar conductivity measurements and other physical properties of these compounds are discussed. Thermal behaviour of all compounds was studied by means of DTA, DTG, TG techniques under static conditions in air. The resultant final products were the metal oxide in all cases. A coupled TG-MS system was used to analysis of princpal volatile thermal decomposition (or fragmentation) products of Co(II) and Ni(II) complexes. The principal volatile mass fragments correspond to: C+, OH+, H2O+, NO+,CO2 + and other.
