| Abstract: The novel complex [Cu4( μ-OH)(Mba)(Phen)4]·(ClO4)2 has been hydrothermally synthesized by Hmba and Phen with copper(Ⅱ), where Hmba=methoxybenzoic acid and Phen=1,10-phenanthroline. The crystal structure of the complex has been determined by X-ray diffraction .The crystal belong to monoclinic system, space group P21/n. The cell parameters are: a=1.149 6(2)nm, b=1.623 9(3) nm, c=1.740 4(4) nm, β=106.52(3)°, V=3.115 1(1) nm3, Z=4, μ(Mo Kα)=16.14 cm-1, F(000)=1 728, R1=0.029 6, wR2=0.075 7 (I>2σ(I)). The two centric copper(Ⅱ) ions are four-coordinated in the distorted planar tetragon arrangement for the complex. A hydroxidion and a methoxybenzoic acid act as the bridge to link two Cu(Ⅱ) ions. Each asymmetric unit is connetcted by weak interaction to form a helix chian. Three-dimensional network is formed through the π-π packing between aromatic rings. The luminescent and electrochemical property of the novel complex has been stuied. CCDC: 749064. | |
