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)^sub 2^]^sub 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)°, β = 99.966(5)°, γ = 101.666(5)°, V= 699.1(4) Å^sup 3^, Z = 2, Dc = 1.614 mg·m^sup -3^, µ = 1.774 mm^sup -1^, F(000) = 348, and final R^sub 1^ = 0.0541, ωR^sub 2^ = 0.1605. X-ray diffraction analysis reveals that the Zn(II) center is six-coordination with a N^sub 2^O^sub 4^ distorted octahedral coordination environment. The Zn(II) complex forms 1D chain structure by the bridge of 4,4'-bipyridine and acetato.
