Five new coordination compounds, namely [Zn(Hbtc)(1,3-bix)(H2O)](n) (1), {Zn-2(mu-O)(btc)(timp)]center dot 3(H2O)}(n) (2), {[Zn-3(4,4'-bibp)(2)(btc)(2)(H2O)(2)]center dot 4(H2O)}(n) (3), {[Ni-3(4,4'-bibp)(2)(btc)(2)(H2O)(2)]center dot 3(H2O)}(n) (4), {[Cu-3(4,4'-bibp)(2)(btc)(2)(H2O)](2)(H2O)}(n) (5), where 1,3 - bix = 1-(3 - (1H -inidazol - 1 - yl)methyl)benzyl)-1H-imidazole, timp - 1-(3,5-di (1H-imidazol-1-yl)phenyl)-1H-imidazole, 4,4'-bibp 4,4'-bisimidazolylbiphenyl, and btc = 1,3,5-benzenetricarboxylate anion, were synthesized under hydrothermal conditions. In compound 1, both 1,3-bix ligand and btc anion act as bidentate bridging ligands, and connect the zinc cations into a one-dimensional chain. In compound 2, timp and btc anions as tridentate ligands coordinate to zinc cations to form a three-dimensional 3,6-connected network. Compounds 3-5 have similar structures, 4,4'-bibp and btc anions act as bidentate and tetradentate ligands, respectively, and coordinate to metal cations to form a three dimensional 4,4-connected network. The luminescence properties for 1-3 and magnetic properties for 4-5 are also discussed in detail.
