Abstract: The title compound, [ZnCl₂(C₁₀H₁₂N₄O₂)]·0.5H₂O, was readily prepared by the reaction between ZnCl₂ and 2-hydroxyimino-N'-[1-(2-pyridyl)ethylidene]propanohydrazide. The Zn atom has a distorted trigonal-bipyramidal geometry with two Cl atoms and one azomethine N atom in the equatorial plane and one pyridine N atom and one amide O atom in the axial positions. In the crystal structure, complex molecules are connected in pairs by N-HCl hydrogen bonds, formed between the amide NH of one molecule and the Cl atom of a neighboring one. Molecular pairs are connected by hydrogen bonds involving the uncoordinated water molecule, which lies on a twofold axis.
