Fund Project:

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)°, V=3973.4(14) Å³, D_c=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 L^2- 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℃.
