Abstract: Reaction of copper (II) salts with nitrobenzoic acids in the presence nicotinamide the nitrobenzoatocopper(II) complexes with nicotinamide are formed. Their composition, spectral, magnetic properties and structure have been studied together with their antimicrobial activity. The stoichiometry of the final product is influenced by the type of nitrobenzoato ligand and 3-nitrobenzoato anion has caused formation of the complex of unusual stoichiometry [Cu(3-NO2bz)2(nia)1(H2O)2] was prepared and studied. The complexes of general formula [Cu(x-NO2bz)2(nia)2(H2O)y] (where x-NO2 = 2-NO2, 4-NO2 and y = 2; or x-NO2 = 3,5-(NO2)2 and y = 1) were obtained for other copper(II) nitrobenzoates. Rather unusual stoichiometry of [Cu(3-NO2bz)2(nia)1(H2O)2] has caused unusual magnetic behaviour and the antimicrobial activity different from those ones of composition [Cu(x-NO2bz)2(nia)2(H2O)y].

Keywords: copper complexes, nitrobenzoato ligand, nicotinamide ligand, crystal structure, antimicrobial activity
