Synthesis and characterization of [Zn-2(4,4 '-bipy)(n)(AcO)(4)] - One-dimensional chain (n=1) and one-dimensional double-chain (n=2) coordination polymers

摘要

Two new Zn-11(mu-4,4'-bipy) coordination polymers with acetate anions, [Zn(4,4'-bipy)(AcO)(2)] (1) and [Zn-2(4,4'-bipy)-(AcO)(4)] (2), have been synthesized. The compounds were characterized with elemental analysis, IR-, H-1 NMR-, C-13 NMR spectroscopy and studied by thermal analysis, fluorescence measurements and x-ray crystallography. The structural studies of compound I suggest the structure is a coordination polymer of zinc(II) consisting of linear double chains formed by bridging 4,4'-bipy ligand and connection of the acetate-bridged centrosymmetric [Zn-2(OAc)(2)](2+) nodes.
