Popis:	A novel series of Mn(II), Co(II) and Cu(II) complexes with some bisazo-dianils (compounds having two N=N and two HC=N groups) containing the pyrimidine moiety were prepared and characterized by elemental and thermal analyses, molar conductance and magnetic moment determination as well as IR, electronic absorption and ESR spectra. The data revealed different geometries around the metal ions, depending on both the ligand and metal ion.
