Cobalt(II) and copper(II) assembling through a functionalized oxamate-type ligand
Two new metal complexes of formula {[Co(Hpcpa)(H2O)3]n� 3/2nH2O} (1) and [Cu2(MeHpcpa)4(MeOH)2] � H2O� 3.68 MeOH (2 )[ H 3pcpa = N-(4-carboxyphenyl)oxamic acid and MeH2pcpa = methyl ester derivative of H3pcpa] have been synthesized and their structures determined by X-ray diffraction. 1 is a neutral zigzag chain of cobalt(II) ions bridged by Hpcpa 2� ligands exhibiting the bidentate/monodentate coordination mode. Each cobalt(II) ion is six-coordinate with three mer positioned water molecules, two oxamate-oxygens from a Hpcpa 2� ligand and a carboxylate-oxygen from another Hpcpa 2� group building a somewhat distorted octahedral surrounding. The intrachain cobalt–cobalt separation is 11.326(2…
