A new coordination polymer, namely [Zn(pdc)(bbi)]n {H2 pdc = 2,3-pyridine dicar- boxylic acid, bbi = 1,1-(1,4-butanediyl)bis(imidazole)}, has been prepared under hydrothermal conditions and characterized by elemental analysis, IR, and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21 /n with a = 8.436(3), b = 16.988(5), c = 12.106(4), β = 92.204(5)°, V = 1733.6(9)3, Z = 4, C17 H17 N5 O4 Zn, Mr = 420.73, Dc = 1.612 g/cm3, F(000) = 864, μ(MoKa) = 0.452 mm-1, the R = 0.0672 and wR = 0.1645. In the mononuclear complex, each Zn(II) is five-coordinated by one carboxylate O and one pyridyl N atoms from one pdc anion, one carboxylate O atom from another pdc anion, and two N atoms from two bib ligands. The Zn(II) ions are connected by pdc ligands to form skeleton chains, and bbi ligands further link them to construct a 2D framework. The thermal and luminescence properties of the complex were also investigated.
