摘　　要：A new terbium(Ⅲ complex Tb(C20H14O3N)3(C12H8N2)（H2O）·H2O has been synthesized with 2-diphenylanine carbonyl benzoic acid and 1,10-phenanthroline as ligands. Crystal data for the complex are as follows: triclinic, space group P1, a =11.6034（6）, b = 16.2465（8）, c = 16.4427（8） ?, α = 73.168（5）o, β = 88.655（4）o, γ = 82.865（4）o, V = 2943.7（3） ?3, Dc = 1.494 g/cm3, Z = 2, μ（MoK α） = 1.272 mm-1, F（000） = 1348, the final R = 0.0535 and w R = 0.0809. The Tb（Ⅲ） ion is coordinated by nine atoms to give a monocapped square antiprism coordination geometry. The complex shows four fluorescence emission bands arising from the transitions of Tb3+: 5D4 → 7F6（491 nm）, 5D4 → 7F5（546 nm）, 5D4 → 7F4（585 nm） and 5D4→7F3（621 nm）. Also reported are the magnetic and thermal stability properties of the complex.
