Abstract
Abstract The title compound of zinc(II) and picolinic acid was synthesized and characterized by X-ray crystallographic and spectroscopic methods. In the structure of [Zn(C5H4NCO2H)(C5H4NCO2)Cl], each zinc atom is coordinated by two nitrogen atoms at ZnN distances of 2.040(8) A and two oxygen atoms, O(1), at ZnO bond lengths of 2.152(5) A, belonging to two picolinate ligands. Coordination number five of the zinc atom is completed by a ZnCl bond [2.221 (3) A]. The O(2)⋯O(2) separation between non-coordinated picolinate oxygen atoms of adjacent polyhedra is 2.41 (1) A. The IR and Raman spectral results confirm the existence of neutral picolinic acid as well as the picolinate anion.
