摘要：

A new europium(III) complex Eu(C20H14O3N)(3) (2,2'-bipy)(H2O)center dot H2O has been synthesized with 2-diphenylanine carbonyl benzoic acid and 2,2'-bipyridine as ligands. Crystal data for the complex are as follows: triclinic, space group P (1) over bar, a = 11.3334(5), b = 16.0883(7), c = 17.0116(8) angstrom, alpha = 70.411(4)degrees, beta= 82.435(4)degrees, gamma = 85.095(4)degrees, V = 2894.0(2) angstrom(3) , D-c = 1.484 g/cm(3) , Z = 2, mu = 1.15 mm(-1) , F(000) = 1320 and the final R= 0.0447 and wR = 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 Eu3+ : D-5(0) -> F-7(1) (592 nm) and D-5(0) -> F-7(2) (616 nm), respectively. Also reported is the magnetic property of the complex. The complex exhibits antiferromagnetism in the temperature range of 300 similar to 2 K.
