The novel europium complex Eu3(dpa dioxide)4·(CF3COO)5·H2O (dpa dioxide = di-2-pyridylamine N,N-dioxide) was prepared by the reaction of Eu(CF3CO2)3 with Dpa dioxide in acetonitrile under 95 ℃ and determined by X-ray single-crystal diffraction. The crystal belongs to monoclinic system, space group C2/c with a = 41.632(8), b = 14.662(3), c = 23.300(4)(A),β= 100.862(5)°, Z = 8, D = 1.775 g/cm3, V = 13968(4)(A)3, F(000) = 7232, the final R = 0.0464 and wR = 0.1168. In this tri-nuclear complex, each europium(Ⅲ) is nine-coordinated to adopt an unequal sphere geometry.
