                                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 Zn-N distances of 2.040(8) Angstrom and two oxygen atoms, O(1), at Zn-O bond lengths of 2.152(5) Angstrom, belonging to two picolinate ligands. Coordination number five of the zinc atom is completed by a Zn-Cl bond [2.221(3) Angstrom]. The O(2)... O(2) separation between noncoordinated picolinate oxygen atoms of adjacent polyhedra is 2.41(1) Angstrom. The IR and Raman spectral results confirm the existence of neutral picolinic acid as well as the picolinate anion.
