Abstract
Seven novel 3D heterometallic coordination compounds, LnCu(nds)(ina)2·H2O [Ln = Eu (1), Ce (2), Er (3), Gd (4), Sm (5), Tb(6), Dy(7); nds = 2,6-naphthanlenedisulfonate; ina = isonicotinic acid], have been synthesized under hydrothermal conditions and characterized by elemental analysis, infrared spectra, thermogravimetric analysis and single-crystal X-ray diffraction analysis. These compounds are isostructural and constructed by the linkages of 2D [Ln(nds)(H2O)]+ layers and Cu(ina)2− chains, which represent the first examples of 3D heterometallic coordination polymers created by the organodisulfonate ligands. Moreover, the complexes exhibit a novel (3,6)-connected net. The luminescence properties of complexes 1, 5 and 6 and the magnetic property of 4 were also investigated.
