| 摘 要： | The title complex, [Ce(BA)3phen]2 (BA = benzoate, phen = 1,10-phenanthroline), was prepared by the reaction of Ce(NO3)3·6H2O, benzoic acid and 1,10-phenanthroline. The complex was characterized by single-crystal X-ray diffraction, elemental analysis, IR spectra and TG-DTG techniques. The results show that the crystal is of triclinic, space group P1 with a = 10.912(2), b = 11.962(3), c = 12.474(3) , α = 104.889(3), β = 93.523(3), γ = 113.332(3)o, C66H46Ce2N4O12, Mr = 1366.90, V = 1420.2(6) 3, Z = 1, Dc = 1.598 g/cm3, μ = 1.652 mm-1, S = 1.024 and F(000) = 682. The final R = 0.0391 and wR = 0.0947 for 4878 observed reflections with I > 2σ(I). The structure of the title complex consists of two Ce(C6H5COO)3(C12H8N2) units, forming a binuclear molecule. Each Ce(III) is coordinated by two O atoms of one bidentate chelating carboxylate group, five O atoms of two bidentate bridging and two tridentate chelating-bridging carboxylate groups, and two N atoms of one 1,10-phenanthroline molecule to complete a distorted monocapped square antiprism geometry. Its thermogravimetric analysis was determined by TG-DTG techniques.
