Synthesis, crystal structure and characterization of a 1D chain coordination polymer of zinc(II) with aroylamide, [Zn(H₂bpb)Cl₂]_n· CH₃OH, (H₂bpb = 1,2-bis(3-pyridylcarboxamide)benzene)

Abstract

A four-coordinate zinc(II) coordination polymer, [ZnCl₂(H₂bpb)] _n · CH₃OH (H₂bpb = 1,2-bis(3-pyridylcarboxylamide)benzene), has been prepared and the crystal structure determined by X-ray diffraction. It crystallizes in the triclinic system, space group with a = 7.898(3) Å, b = 11.792(4) Å, c = 11.911(4) Å, α = 76.051(4)°, β = 89.919(4)°, γ = 78.267(4)°, V = 1052.9(7) Å, Z = 2. The crystal structure consists of chains of complex zig-zaging along the b lattice translation. Fluorescent and thermal properties of the complex were also investigated.
