A new cadmium(II) coordination polymer with benzenetricarboxylate{Cd2- (Htma)2(H2O)2}}n 1 (Htma = 1-carboxybenzene-2,4-dicarboxylate) has been synthesized by hydro- thermal reaction. 1 crystallizes in triclinic, space group P?with a = 6.9990(8), b = 7.0564(8), c = 10.096(1) ? = 83.438(1), = 86.357(2), = 69.233(2)? V = 463.02(9) 3, Dc = 2.428 g/cm3, F(000) = 328, Mr = 677.08, m(MoKa) = 2.382 mm-1, Z = 1, the final R = 0.0284 and wR = 0.0772 for 1540 observed reflections (I≥2s(I)). The structure of 1 consists of centrosymmetric dinuclear units with all metal centers being six-coordinated, which adopt a distorted octahedral configuration and lead to the formation of three-dimensional microporous framework with size of about 3 ??8 ? Fluoerescent measurement showed that 1 exhibits intense fluorescent emission.
