SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF A Zn(II) COORDINATION POLYMER BASED ON 4,4’-BIPYRIDINE AND ACETATO

Abstract

A novel Zn(II) coordination polymer, [Zn(bpy)(acetato)2]n (bpy = 4,4’-bipyridine), has been synthesized and characterized by elemental analysis and single-crystal X-ray diffraction. The Zn(II) coordination polymer is triclinic, space group P-1 with a = 8.046(3) Å, b = 9.161(3) Å, c = 10.663(3) Å, α = 109.769(4)º, β = 99.966(5)º, γ = 101.666(5)º, V= 699.1(4) Å3, Z = 2, Dc = 1.614 mg·m-3, μ = 1.774 mm-1, F(000) = 348, and final R1 = 0.0541, ωR2 = 0.1605. X-ray diffraction analysis reveals that the Zn(II) center is six-coordination with a N2O4 distorted octahedral coordination environment. The Zn(II) complex forms 1D chain structure by the bridge of 4,4’-bipyridine and acetato.
