A new complex Cu2(phen)2[C7H8(COO)2]2 (H2O)4:5 (1) has been synthesized, with the dianion of bicyclo[2.2.1] hept-2-ene-5,6-dicarboxylic acid [C7H8(COOH)2] (LH2) and 1,10-phenanthroline (phen) as ligands. In 1, L2- anions link Cu(II) cations to form two binuclear structure units, in which each Cu(II) cation is coordinated by five donor atoms to give a distorted square-pyramidal geometry. The magnetic data of 1 show that it exhibits weak antiferromagnetic properties at low temperature. When the excitation wavelength is at 470 nm, it has an intense photoluminescence. In addition, the cyclovoltamm...
