Abstract / Full Text

New iron(II) and copper(II) coordination compounds with 2,6-bis[1-(phenylimino)ethyl]pyridine (L1), Fe(L1)2SO4·H2O, Fe(L1)2(ClO4)2, Cu(L1)Cl2, and Cu(L1)2Br2·2H2O, were synthesized. The compounds were identified and investigated using CHN analysis and electronic spectroscopy (diffuse reflectance spectroscopy), IR spectroscopy, XRD, and static magnetic susceptibility. Antiferromagnetic exchange interactions between paramagnetic centers are observed in all iron and copper complexes in the ranges 80–420 and 1.77–300 K, respectively. Evaluation of the cytotoxic activity of copper(II) complexes showed that the Cu(L1)2Br2 complex (IC50 26.7 μmol/L) exhibits the highest activity against the human breast adenocarcinoma cell line (MCF-7).
