A new dinuclear copper(II) complex [Cu2(L)2(phen)2]·5H2O (1) with bicycle[2.2.1]hept- 2-en-5, 6-dicarboxylic acid (H2L) and 1,10-phenanthroline (phen) as ligands has been synthesized in the mixed solvents of ethanol and water. It crystallizes in the monoclinic space group P21/c, with a = 17.925(4), b = 19.908(4), c = 11.235(2) Å, β = 97.65(3)º, V = 3973.4(14) Å3, Dc = 1.552 g/cm3, Z = 8, F(000) = 1910, the final GOOF = 1.056, R = 0.0519 and wR = 0.1293. The crystal structure shows that the whole molecule consists of two independent dinuclear units, in which two copper ions are bridged by two μ2-η1:η0-3-carboxylate groups of L2- anions. The fluorescence and thermal stability properties of 1 were studied. The results show that 1 has an intense fluorescent emission at around 381 nm. The TG analysis shows that 1 is stable below 143 ℃.
