A new complex Cu 2 (phen) 2 [C 7 H 8 (COO) 2 ] 2 (H 2 O) 4:5 (1) has been synthesized, with the dianion of bicyclo[2.2.1] hept-2-ene-5,6-dicarboxylic acid [C 7 H 8 (COOH) 2 ] (LH 2 ) and 1,10-phenanthroline (phen) as ligands. In 1, L 2- 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 cyclovoltammetric electron transfer is quasi reversible in the electrode reaction of 1, two electrons being involved in the reaction corresponding to Cu(II)=Cu(0)
