摘　　要：A new europium(Ⅲ)complex Eu(C_(20)H_(14)O_(3)N)_(3)(2,2'-bipy)(H2O)·H2O has been synthesized with2-diphenylanine carbonyl benzoic acid and 2,2'-bipyridine as ligands.Crystal data for the complex are as follows:triclinic,space group Pi,a=11.3334(5),b=16.0883(7),c=17.0116(8)A,α=70.411(4)o,β=82.435(4)o,γ=85.095(4)o,V=2894.0(2)A^(3),Dc=1.484 g/cm^(3),Z=2,μ=1.15 mm^(-1),F(000)=1320 and the final R=0.0447 and w R=0.0578.The Eu(Ⅲ)ion is coordinated by nine atoms to give a monocapped square antiprism coordination geometry.The complex shows two intense fluorescence emission bands arising from the transitions of Eu^(3+):^(5)D0→^(7)F_(1)(592 nm)and ^(5)D_(0)→^(7)F_(2)(616 nm),respectively.Also reported is the magnetic property of the complex.The complex exhibits antiferromagnetism in the temperature range of 300~2 K.
