摘　　要：A new binuclear cage-like samarium(Ⅲ) complex Sm2(C7H4ClCOO)6(C(12)H8N2)2(H2O)2(1) with samarium(Ⅲ) nitrate, m-chlorobenzoic acid and 1,10-phenanthroline(phen) was synthesized. It crystallizes in the triclinic space group P1, with a = 8.0217(2), b = 12.9037(4), c = 15.3764(5) ?, α = 85.373(3)o, β = 84.396(3)o, γ = 80.443(3)o, V = 1558.64(8) ?~3, Dc = 1.636 g/cm^3, Z = 2, F(000) = 806, the final GOOF = 1.051, R = 0.0754 and wR = 0.1388. The whole molecule consists of two samarium ions bridged by four m-chlorobenzoic acid anions. The Sm(III) ion is coordinated by eight atoms to give a distorted square antiprism coordination geometry. The TG analysis and fluorescent properties of 1 were studied.
