Six new coordination compounds, namely [Co(H2bptc)]n(1), [Mn(H2bptc)]n(2), [Cd2(bptc)(phen)2(H2O)2]n(3), [Eu2(cpa)3(DMF)2]n(4), [Nd2(cpa)3(DMF)2]n(5) and [Pr2(cpa)3(DMF)2]n(6) (bptc4−= biphenyl-2,2′,4,4′-tetracarboxylate anion, phen =1,10-phenanthroline, cpa2−= 4-chloroisophthalic acid anion) were synthesized under hydrothermal conditions. Their structures have been determined by single-crystal X-ray diffraction analysis and further characterized by elemental analysis, IR spectra, and thermogravimetric analysis. Co and Mn compounds are isostructural, and possess a three-dimensional 5, 5-connected network. In Cd compound, multicarboxylate ligand H4bptc link Cd centers to generate a two-dimensional 4, 4-cnet structure with phen acting as terminal ligand. Eu, Nd, and Pr compounds have similar structures, and cpa2−ligands link lanthanide cations to generate a two-dimensional sheet structure. Magnetic susceptibility measurements indicate that the Co compound has a dominating ferromagnetic coupling between Co(ii) ions, and Mn compound exhibits antiferromagnetic coupling between Mn(ii) ions. Furthermore, their luminescent properties are also determined in the solid state at room temperature. [ABSTRACT FROM AUTHOR]
