Synthesis, Crystal Structure and Properties of a New Zn(Ⅱ) Coordination Polymer Constructed from 2,3-Pyridine Dicarboxylic Acid and 1,1'-(1,4-Butanediyl)bis(imidazole)
摘要:
A new coordination polymer, namely[Zn(pdc)(bbi)]n {H2pdc=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) Å, β=92.204(5)°, V=1733.6(9) Å3, Z=4, C17H17N5O4Zn, 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.
