A novel two-dimensional metal organic coordination compound based on flexible 1,3,5-tri（4-carboxyphenoxy）benzene （HaTCPB）, {[Mgl.5（TCPB）（DMF）（H20）]＇（DMF）}n （1）, has been prepared and structurally charac...A novel two-dimensional metal organic coordination compound based on flexible 1,3,5-tri（4-carboxyphenoxy）benzene （HaTCPB）, {[Mgl.5（TCPB）（DMF）（H20）]＇（DMF）}n （1）, has been prepared and structurally characterized by single-crystal X-ray diffraction, TGA, and PXRD measurements. Complex 1 crystalizes in triclinic, space group Pi with a = 10.2521（6）, b = 11.0974（7）, c = 16.1113（9） A, C33H31Mg1.5N2012, Mr = 684.06, V= 1669.46（17） A3, Z = 2, Dc = 1.361 g·cm^-3, p = 0.129 mm^-1, F（000） = 714, 3.06≤0≤25°, λ（MoKa） = 0.71073 A, T= 273（2） K, the final R = 0.0386, wR = 0.0892 and S = 1.031. X-ray diffraction analysis reveals that complex 1 possesses a two-dimensional framework constructed by trinuclear Mg SBUs and three-connected TCPB3- linker. In addition, the solid state luminescent property of complex 1 was also investigated at room temperature.展开更多
