A new copper(II)complex Cu2(L)4(2,2-bipy)2(H2O)2(1)has been synthesized with2-benzoylbenzoic acid(HL)and 2,2-bipyridin as ligands.The crystal belongs to a monoclinic system with space group Cc,a=13.9979(11),b=15.9888(13),c=30.306(3),β=100.8700(10)o,V=6661.1(10)3,Dc=1.372 g/cm3,Z=8,F(000)=2840,the final GOOF=1.018,R=0.0685,and wR=0.1731.There are two mononuclear Cu(L)2(2,2-bipy)(H2O)units in the crystal of 1.Each Cu(II)cation is coordinated by five atoms.The magnetic and fluorescent properties of 1 were studied.The results show that 1 exhibits weak paramagnetism,and when the excitation wavelength is at 616 nm,it has an intense fluorescent emission band around 482 nm.
