摘　　要：A coordination polymer of [Tb(ntb)]n(1) based on 4,4’,4’’-nitrilotribenzoate ligand(ntb3–) was synthesized. Compound 1 crystallizes in monoclinic system, space group C2/c with a = 13.7318(4), b = 27.5628(9), c = 5.4046(2) ?, β = 111.142(3)°, V = 1907.88(12) ?3, Z = 4, C21H12NO6Tb, Mr = 533.24, Dc = 1.856 g/cm3, μ = 3.745 mm–1, F(000) = 1032, the final R = 0.0184 and wR = 0.0456 for 1883 observed reflections with Ⅰ > 2s(Ⅰ). In compound 1, the eight-coordinated Tb(III) atoms are bridged by carboxylate groups of ntb3– ligands to generate a one-dimensional Tb-carboxylate chain, which is further linked by the ntb3– ligands to form a three-dimensional structure. Compound 1 exhibits characteristic Tb(Ⅲ) luminescent emissions in the solid state.
