A new metal-organic coordination polymer [Zn2(trz)2(mpda)(H2O)]n(1, trz = 1,2,4-triazole, H2 mpda = 2,6-dimethylpyridine-3,5-dicarboxylic acid) was synthesized and characterized by single-crystal X-ray analyse...A new metal-organic coordination polymer [Zn2(trz)2(mpda)(H2O)]n(1, trz = 1,2,4-triazole, H2 mpda = 2,6-dimethylpyridine-3,5-dicarboxylic acid) was synthesized and characterized by single-crystal X-ray analyses. The crystal is of monoclinic system, space group P21/n, a = 9.619(3), b = 8.920(3), c = 22.159(6), β = 96.897(4)°, V = 1887.3(9)3, Z = 4, Mr = 478.04, D3 c = 1.682 Mg/m, F(000) = 960, the final R = 0.0264 and wR = 0.0870(I 2σ(I)). Compound 1 consists of {[Zn4(trz)4]4+}n layers, which are further connected by mpda2- to complete a three-dimensional structure. The title compound exhibits luminescence at λmax = 415 nm upon excitation at 364 nm.展开更多
