Metal complexes of pyrimidine-derived ligands — Part 6. Bischelates of cobalt(II), nickel(II) and monochelates of copper(II) with 3, 5-dimethyl-1-(4′, 6′-dimethyl-2′-pyrimidyl)pyrazole, a potential antitumour agent

Summary

Cobalt(II), nickel(II) and copper(II) complexes of 3, 5-dimethyl-1-(4′, 6′-dimethyl-2′-pyrimidyl)pyrazole (DPymPz) have been synthesized and characterized. Magnetic and electronic spectral features show that both [M(DPymPz)2X2]·nH2O [M=cobalt(II) or nickel(II), X=Cl, Br, I, SCN, NO3, ClO4 or BF4 andn=0 or 2] and [Cu(DPymPz)X2(H2O)2] (X=Cl, Br or SCN) are essentially octahedral species. The i.r. spectra indicate that DPymPz is a neutral bidentate ligand being the pyrazolyl and one pyrimidyl ring nitrogen. The X is bonded to the central metal ion in a majority of the complexes.
