| Abstract: A new coordination polymer [Zn(C2O4)(1,3-bix)]n (1, H2C2O4=oxalic acid, 1,3-bix=1,3-bis(imidazol-1-ylmethyl)-benzene) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, TG and single-crystal X-ray diffraction. The complex crystallizes in triclinic, space group P1 with a=0.885 8(2) nm, b=0.956 8(2) nm, c=1.019 6(3) nm, α=67.476(3)°, β=66.281(3)°, γ=77.280(3)°, V=0.780 0(3) nm3, C16H14N4O4Zn, Mr=391.68, Dc=1.668 g·cm-3, μ(Mo Kα)=1.605 mm-1, F(000)=400, Z=2, the final R=0.025 5 and wR=0.060 9 for 2 760 observed reflections (I>2σ(I)). In the crystal structure, the zinc atom is six-coordinated with four carboxylate oxygen atoms from two different C2O42- ligands and two nitrogen atoms from two different 1,3-bix ligands, showing a distorted octahedral geometry. Furthermore, it exhibits 3D supramolecular network structure through hydrogen bonding and π-π stacking interactions. Moreover, its luminescent property has been investigated in the solid state.
