COMPLEXES WITH AMIDES. PART 2. SYNTHESIS, SPECTROSCOPIC, MAGNETIC AND BIOLOGICAL CHARACTERIZATION OF Ni(II) AND Cu(II) COMPLEXES WITH POLYFUNCTIONAL AMIDES

摘要

A series of new complexes of Ni(II) and Cu(II) with N-(2-chloro-pyrid-3-yl)-4-chlorobenzamide (CPC, 1), N-(3,5-dichloro-pyrid-2-yl)-berizamide (DCB, 2) and with N-(3-chloro-pyrid-2-yl)-furylamide (CPF, 3) were synthesised and characterised. The bonding and stereochemistry of the complexes were characterised by IR, EPR, electronic spectroscopy, magnetic susceptibility at room temperature and conductivity measurements. The results concerning the thermal behaviour of Cu(II) complex with DCB are reported. All ligands behave as bidentate and coordinate through the pyridinic nitrogen and amidic oxygen atoms. Complexes and ligands show no biological activity against Proteus, Escherichia Coli and Staphylococcus.
