A dinuclear copper(II) complex of formula [{Cu(bipy)(bzt)(OH2)}2(μ-ox)] (1) (where bipy = 2,2′ -bipyridine, bzt = benzoate and ox = oxalate) was synthesized and characterised by diffractometric (powder and single-crystal XRD) and thermogravimetric (TG/DTG) analyses, spectroscopic techniques (IR, Raman, ESR spectroscopy (EPR) and electronic spectroscopy), magnetic measurements and d. functional theory (DFT) calculations The anal. of the crystal structure revealed that the oxalate ligand is in bis(bidentate) coordination mode between two copper(II) centers. The other four positions of the coordination environment of the copper(II) ion are occupied by one water mol., a bidentate bipy and a monodentate bzt ligand. An inversion center located on the ox ligand generates the other half of the dinuclear complex. Intermol. hydrogen bonds and π-π interactions are responsible for the organization of the mols. in the solid state. Molar magnetic susceptibility and field dependence magnetization studies evidenced a weak intramol.-ferromagnetic interaction (J = +2.9 cm-1) between the metal ions. The sign and magnitude of the calculated J value by d. functional theory (DFT) are in agreement with the exptl. data.
