Dichlorido[2-(3,5-dimethyl-1H-pyrazol-1-yl-κN(2))quinoline-κN]zinc

Abstract

The Zn(II) atom in the title compound, [ZnCl(2)(C(14)H(13)N(3))], is coordinated by a Cl(2)N(2) donor set defined by quinoline and pyrazole N atoms of the chelating ligand and two Cl atoms. Distortions from the ideal tetra-hedral geometry relate to the restricted bite angle of the chelating ligand [N-Zn-N = 78.54 (12)°]. In the crystal, mol-ecules are connected into a three-dimensional structure by C-H⋯Cl inter-actions, involving both Cl atoms, and π-π inter-actions that occur between the pyrazole ring and each of the pyridine and benzene rings of the quinoline residue [inter-centroid distances = 3.655 (2) and 3.676 (2) Å].
