title: Photoluminescent metal-organic polymer constructed from trimetallic clusters and mixed carboxylates.
abstract: The solvothermal reaction of zinc acetate dihydrate with a mixture of benzene-1,4-dicarboxylic acid (H(2)BDC) and benzene-1,3,5-tricarboxylic acid (H(3)BTC) in a solution containing N,N'-dimethylformamide (DMF), absolute ethanol, and chlorobenzene gave rise to a metal-organic polymer, Zn(3).BDC.2BTC.2NH(CH(3))(2).2NH(2)(CH(3))(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 (C(17)H(20)N(2)O(8)Zn(1.5)): monoclinic, space group P2(1)/n, cell dimensions a = 11.6171(3) A, b = 14.2456(4) A, c = 12.6426(3) A, beta = 107.030(2) degrees, V = 2000.51(9) A(3), and Z = 4.
