摘　　要：[Ce(CH3COO)2(NO3) (phen)]2, Mr=1000. 84. The crystal is monoclinic, lattice type C-centered, space group C2/m, with a=15. 444 (6), b= 12. 273(5), c=12. 776(5) A, β= 131. 89(2)°, Z= 2, Dc= 1, 844 g/cm3, μ(MoKa)=25. 69 cm-1, F(000)=980. 00, V= 1802 (1 ) A, R=0.024, Rw=0. 032. Themolecule of the complex is a dimer with C2h symmetry and the molecular center lies onthe special position 2/m. The Ce(Ⅲ) ion is nine-coordianted to one bidentate nitrategroup, five oxygen atoms of acetates and two nitrogen atoms of 1, 10-phenanthroine(phen).
