Synthesis, crystal structure, and properties of a new zinc coordination polymer [Zn(PMP)₂Cl]_n

Abstract

A new coordination polymer [Zn(PMP)₂Cl] _n (PMP = 1-phenyl-3-methyl-5-pyrazolone) has been prepared by the reaction of zinc chloride and PMP, and characterized by elemental analysis, IR, UV, and fluorescence spectra, TG/DTA, and electrochemical analysis. Single crystal X-ray diffraction revealed that the complex is monoclinic, space group P 2(1)/n, with a = 10.850(17), b = 17.578(2), c = 10.997(18) Å, β = 104.999(3)°, V = 2025.8(5) ų, Z = 4, D_c = 1.470 mg m⁻³, F(000) = 920, goodness-of-fit = 0.905, and R ₁ = 0.0441. The complex is a 1-D coordination polymer, and the coordination geometry of Zn(II) is a distorted tetrahedron.
