摘　　要：A new binuclear cage-like yttrium(Ⅲ) complex Y2(TMBA)6(phen)2(1) with yttrium nitrate, 2,4,6-trimethylbenzoic acid(TMBA) and 1,10-phenanthroline(phen) was synthesized. It crystallizes in the triclinic space group P1 with a = 11.9086(15), b = 12.4843(17), c = 14.2101(18) ?, α = 104.977(4), β = 111.750(4), γ = 95.874(5)o, V = 1848.8(4) ?3, Dc = 1.363 g/cm3, Z = 1, μ(Mo Ka) = 1.627, F(000) = 788, the final GOOF = 1.039, R = 0.0353 and w R = 0.0826. The whole molecule consists of two yttrium ions bridged by four 2,4,6-trimethylbenzoic acid anions. The Y(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.
