The novel complex [Zn2(Mba)3(Phen) 2EtOH)]·ClO4 (Hmba = methoxybenzoic acid, Phen = 1,10-phenanthroline, EtOH = ethanol) was synthesized by hydrothermal reactions, and its structure was determined by X-ray diffraction. The crystal belongs to the triclinic system, space group P1 with a = 1.15362(1), b = 1.3655(3), c = 1.61451(1) nm, α = 72.842(2), β = 83.259(3), γ = 72.083(2)°, V = 2.3112(6) nm3, Z = 2, μ(MoKα) = 11.71 cm -1, F(000) = 1120, R = 0.0552 and wR = 0.1157 (I > 2σ(I)). The two centric zinc(II) ions in the complex locate in a distorted octahedral coordination geometry and a distorted trigonal bipyramid coordination geometry, respectively. Two bridging bidentate carboxyl groups and a μ2-O carboxyl group from three methoxybenzoic acids act as the bridge to link two Zn(II) ions. The asymmetric units are connected by π- π packing interactions between aromatic rings to form a three-dimensional supramolecular network. The experimental results show a good fluorescence property for the complex. Source
