摘　　要：Terbium p-chlorobenzoate complex with 1,10-phenanthroline, [Tb( p-ClBA)_3phen]_2 (1) has been obtained in the ethanol solution, where p-ClBA=p-chlorobenzoate and phen=1,10-phenanthroline. It crystallizes in the triclinic system, space group P1, a=1.008 1(2) nm, b=1.185 7(2) nm, c=1.431 1(3) nm, α=110.826(4)°, β=96.436(4)°, γ=101.737(4)°, Z=2. The two Tb(Ⅲ) ions are linked by four carboxylate groups through their bidentate bridging modes, forming a dimeric unit with crystallographic inversion center. Each terbium ion has an eight-coordinate geometry with four of the coordination sites occupied by four oxygen atoms from the four bridging carboxylates, respectively, two oxygen atoms from bidentate carboxylate, and the remaining positions occupied by two nitrogen atoms from a 1,10-phenanthroline molecule. The Tb(Ⅲ) ion adopt a distorted square antiprism coordination geometry. The excitation and luminescence data observed at room temperature show that the title complex emits very intensive green fluorescence under ultraviolet light. The result of thermal analysis indicates the complex [Tb(p-ClBA)_3phen]_2 is quite stable to heat. CCDC: 221921.Terbium p-chlorobenzoate complex with 1,10-phenanthroline, [Tb（p-ClBA）3phen]2 （1） has been obtained in the ethanol solution, where p-C1BA=p-chlorobenzoate and phen=1,10-phenanthroline.
