Abstract
Novel three Cu(II) complexes {[Cu2(MeOsba)4(H2O)2] (1, HMeOsba = 2-methoxy-5-sulfamoylbenzoic acid), [Cu(MeOsba)2(2a5mp)2].3H2O (2, 2a5mp = 2-amino-5-methylpyridine) and [Cu(Clsba)2(2amp)2].2H2O (3, 2amp = 2-picolylamine, HClsba = 2,4-dichloro-5-sulfamoylbenzoic acid)} were synthesized. The structure of 1–3 characterized by FT-IR, AAS, X-ray crystallographic analysis, UV, molar conductivity and magnetic moment. All complexes (1–3) formed crystals in the P-1 space group and the triclinic crystal system. The symmetric units of complexes (1–3) contains two Cu(II) cations, four MeOsba anions as bridges and two aqua ligands for 1, one Cu(II) cations, two MeOsba anions, two 2a5mp and three uncoordinated water molecules for 2 and one Cu(II) cations, two Clsba anions, two 2amp and three uncoordinated water molecules for 3. The structure of 1–3 have a crystallographic inversion centre.
