Syntheses, crystal structures and magnetic properties of tungstato- and molybdo-bridged dinuclear copper(II) complexes

Abstract: Two new dinuclear copper(II) complexes, [Cu2(bpca)2(WO4) (H2O)2] · H2O (1) and [Cu2(bpca)2(MoO4) (H2O)2] · H2O (2) [bpca = bis(2-pyridylcarbonyl)amide anion], have been synthesized and their magnetic behavior investigated as a function of temperature. The structures of 1 and 2 have been determined by single-crystal X-ray diffraction. Complexes 1 and 2 are both 3D supramolecules with intermolecular hydrogen-bonding and p-p stacking interactions. The magnetic susceptibilities measured over the range 2-300 K show ferromagnetic interaction between the two copper(II) ions in 1, while there is antiferromagnetic interaction between the two copper(II) ions in 2. Based on the Hamiltonian written as Ĥ = -2JS1 .S2, best fitting for the experimental data leads to J = 0.557 cm-1 (1) and -77.2 cm-1 (2).
