摘要
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.
