Abstract: The complex [Tb2(ClC6H4COO)6(2,2′-bipy)2]·(ClC6H4COOH)·(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)°, β=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.
