Abstract

New water-soluble copper(II) bis-N,O-chelate complexes [Cu(L2)2Cl2] (I), [Cu2(L1)2Cl4] (II), and [Cu(L1)2Cl]2[CuCl4] (III) (L1, L2 = pyridyl-containing phospholane oxides) were prepared from N,O-ligands. The complexes were characterized by physicochemical methods (mass spectrometry, IR spectroscopy, elemental analysis, and X-ray diffraction (CIF files CCDC nos. 1976723 (I), 1976724 (II), and 1974303 (III)). The physicochemical properties of the products were studied and the molecular and crystal structures were established. The cytotoxicity against M-HeLa cancer cell lines and Chang liver normal cell lines was determined for the binuclear complex [Cu2(L1)2Cl4].
