Nicotinamide-acetylsalicylato complexes of Co II , Ni II , Cu II , and Zn II were synthesised and their structural properties were investigated by employing elemental analysis, magnetic susceptibilitiy, solid state UV-vis, direct injectionprobe mass, FTIR and thermoanalytic TG-DTG methods. It was found that ratio of metal:ligand:ligand is 1:2:2 and thedecomposition of each complex starts with dehydration and follows by decomposition of the nicotinamide and acetylsalicylato, respectively. The thermal dehydration of the complexes takes place in steps from one to two. The decomposition mechanism and thermal stability of the investigated complexes are interpreted in terms of their structures. Thefinal decomposition products are found to be the respective metal oxides
