Experimental

R factor = 0.050; wR factor = 0.124; data-to-parameter ratio = 18.4. The ZnII atom in the title compound, [ZnCl2(C14H13N3)], is coordinated by a Cl2N2 donor set defined by quinoline and pyrazole N atoms of the chelating ligand and two Cl atoms. Distortions from the ideal tetrahedral geometry relate to the restricted bite angle of the chelating ligand [N—Zn—N = 78.54 (12)]. In the crystal, molecules are connected into a three-dimensional structure by C—H Cl interactions, invol-ving both Cl atoms, and – interactions that occur between the pyrazole ring and each of the pyridine and benzene rings of the quinoline residue [intercentroid distances = 3.655 (2) and 3.676 (2) Å].
