A new europium(III) complex: bis(4,4'-dimethyl-2,2'-bipyridinato)-tris(nitrato-o,o')-europium(III) was prepared by the method of solvothermal synthesis, and its mononuclear crystal structure was determined by X-ray diffraction. The crystal structure of the title compound crystallized in monoclinic, space group C2/c, with a=21.71(5) ?, b=10.203(18) ?, c=16.08(3)?, ?=118.19(11)°, Z=4, Dc=1.630Mg/m3, V=3139(11)?-3. The fluorescent properties show that the compound may be a candidate of red light material for its strong emission at 616 nm under ultraviolet radiation of 321 nm.
