摘要: A new metal-organic coordination polymer [Zn₂(trz)₂(mpda)(H₂O)]_n (1, trz=1,2,4-triazole, H₂mpda=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/c, a=9.619(3), b=8.920(3), c=22.159(6)Å, β=96.897(4)°, V=1887.3(9)Å³, Z=4, M_r=478.04, D_c=1.682 Mg/m³, 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 mpda^2- to complete a three-dimensional structure. The title compound exhibits luminescence at λ_max=415 nm upon excitation at 364 nm.
