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.

In the crystal, two neighboring Tb (III) ions are bridged by four m-chlorobenzoic acid anions, and their end positions 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. 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.
