Crystal Structure and Luminescent Property of a New Heterometallic Coordination Polymer Based on 1D –{Ca–(COO)2–Cu–(COO)2–Ca}n– Chains

A new heterometallic coordination polymer, namely [CuCa(tdc)2(DMA)(H2O)2]n (1, H2tdc = 2,5-thiophenedicarboxylic acid, DMA = N, N-dimethylacetamide) has been solvothermally synthesized by the reactions of CuCl2, CaCl2, and H2tdc. X-ray structural analysis reveals that compound 1 features a 3D heterometallic framework based on one-dimensional –{Ca–(COO)2–Cu–(COO)2–Ca}n– chains. Moreover, the luminescent properties of compound 1 and desolvated 1 were also investigated at room temperature.
