摘　　要：The complex[Tb_2(ClC_6H_4COO)_6(2,2'-bipy)_2]·(ClC_6H_4COOH)·(H_2O)with m-chlorobenzoic acid and 2,2'-bipy -ridine as ligands has been synthesized by means of hydrothermal way.Crystal data for this complex are as follows: monoclinic,space group P1,a=1.143 9(4) nm,6=1.211 6(4) nm,c=1.419 9(5) nm,α= 103.600(6)°,β=95.382(3)°,γ= 99.506(4)°,V=1.8684(10)nm^3,D_c=1.692 g·cm^(-3),Z=2,μ(Mo Kα)=2.236 mm^(-1),F(000)=943,final discrepancy factors R_1=0.052 0,wR_2=0.118 6.In the crystal,two neighboring Tb(Ⅲ) ions are bridged by four m-chlorobenzoic acid anions,and their end positions coordinate with one 2,2'-bipyridine molecule and one m-chlorobenzoic acid anions, respectively,giving a binuclear cage structure,of which the spacing between Tb(Ⅲ)…Tb(Ⅲ) is 0.408 1 nm.Each Tb(Ⅲ) ion coordinates with two nitrogen atoms and six oxygen atoms,giving an eight-coordinated distorted square antiprism geometry.The luminescent property of the complex is also studied.The complex [Tb2（ClC6H4COO）6（2,2＇-bipy）2] （C1C6H4COOH）＇（H2O）with m-chlorobenzoic acid and 2,2＇- bipy-ridine as ligands has been synthesized by means of hydrothermal way. Crystal data for this complex are as follows： monoclinic, space group P1, a=1. 143 9（4） nm, b=1.211 6（4） nm, c=1.419 9（5） nm, α=103.600（6）°, /3=95.382（3）°, γ= 99.506（4）° , V=1.868 4（10） nm3, Dc=1.692 g·cm^-3, Z=2,μ（Mo Kα）=2.236 mm^-1, F（000）=943, final discrepancy factors R1=0.052 0, wR2=0. 118 6. In the crystal, two neighboring Tb（Ⅲ） ions are bridged by four m-chlorobenzoic acid anions, and their end positions coordinate with one 2,2＇-bipyridine molecule and one m-chlorobenzoic acid anions, respectively, giving a binuclear cage structure, of which the spacing between Tb（Ⅲ）.Tb（Ⅲ） is 0.408 1 nm. Each Tb（Ⅲ） ion coordinates with two nitrogen atoms and six oxygen atoms, giving an eight-coordinated distorted square antiprism geometry. The luminescent property of the complex is also studied.
