The title rare earth complex was synthesized in the mixed solvent of distilled water and anhydrous alcohol, containing the acetylacetone and phenanroline etc, and characterized by means of IR spectromety and X-ray structural analysis. The crystallography data: C_ 29H_ 25N_6O_9Ce, M_r=741.67, moloclinic, a=1.1110(2) nm, b=0.9834(2) nm, c=1.3449(3) nm, β=102.03(°), V=1.4371(5) nm 3, Z=2, D_c=1.714 kg·m -3, F(000)=742, μ(Mo Kα)=1.650 mm -1, R=0.042. The results shows that the 10 coordination sites around Ce 3+ of the complex are respectively occupied by six oxygen atoms (from two NO_3 - and one chelate acetylacetone) and four nitrogen atoms (from phenanrolines). The evidence of the chelate coordinate mode of acetylacetone with the rare earth cation of Ce +3 was discussed.
