二水合乙酸锌与苯-1，4-二甲酸（H2 BDC）和苯-1，3，5-三甲酸（H3 BTC）在N，N '-二甲基甲酰胺（DMF）、无水乙醇和氯苯的溶剂热反应中生成金属有机聚合物Zn-3.BDC·2BTC·2NH（CH 3）（2）·2NH（2）（CH 3）（2）。该聚合物的结构具有独特的三维骨架，具有三锌簇，BDC和BTC单元共连接簇。此外，该金属有机聚合物在室温下表现出强的光致发光，并且主发射带在约430 nm（λ（ex）= 325 nm）处。该化合物（C17 H2ON 2 O 8 Zn1.5）的晶体数据：单斜晶系，空间群P2（1）/n，晶胞尺寸a = 11.6171（3）埃，B = 14.2456（4）埃，c = 12.6426（3）埃，β = 107.030（2）度，V = 2000.51（9）埃（3），Z = 4。
The solvothermal reaction of zinc acetate dihydrate with a mixture of benzene-1,4-dicarboxylic acid (H2BDC) and benzene-1,3,5-tricarboxylic acid (H3BTC) in a solution containing N,N'-dimethyl-formamide (DMF), absolute ethanol, and chlorobenzene gave rise to a metal-organic polymer, Zn-3.BDC.2BTC.2NH(CH3)(2).2NH(2)(CH3)(2). The structure of this polymer possesses a unique three-dimensional framework with tri-zinc clusters, and BDC and BTC units colinking the clusters. Moreover, this metal-organic polymer exhibits strong photoluminescence at room temperature, and the main emission band is at about 430 nm (lambda(ex) = 325 nm). Crystal data for this compound (C17H2ON2O8Zn1.5): monoclinic, space group P2(1)/n, cell dimensions a = 11.6171(3) Angstrom, b = 14.2456(4) Angstrom, c = 12.6426(3) Angstrom, beta = 107.030(2)degrees, V = 2000.51 (9) Angstrom(3), and Z = 4.
