| Abstract: A new metal-organic coordination polymer [Zn(pzdc)(bix)0.5(H2O)]n(1) (H2pzdc=pyrazine-2,3-dicarboxylic acid, bix=1,4-bis(imidazol-1-ylmethyl)-benzene) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, UV spectrum and single-crystal X-ray diffraction. The complex crystallizes in triclinic, space group P1 with a=0.737 27(8), b=1.004 45(12), c=1.079 10(13) nm, α=113.771(2), β=102.005(2), γ=93.586(2)°, V=0.705 71(14) nm3, C13H11N4O5Zn, Mr=368.63, Dc=1.735 g·cm-3, μ(Mo Kα)=1.773 mm-1,F(000)=374, Z=2, the final R=0.027 6 and wR=0.067 7 for 2 460 observed reflections (I>2σ(I)). In the crystal structure, 1 shows a two-dimensional layer structure bridged by pzdc and bix ligands. Furthermore, it exhibits a 3D supramolecular network through hydrogen bonding and π-π stacking interactions. Moreover, its luminesent property has been investigated in the solid state.
