ABSTRACT
The ZnII atom in the title compound, [Zn(C2H3O2)2(C14H13N3)], is coordinated by an N2O3 donor set defined by the quinolinyl- and pyrazolyl-N atoms of the chelating heterocyclic ligand, and three carboxylate-O atoms derived from the monodentate and bidentate carboxylate ligands. Distortions from the ideal square-pyramidal coordination geometry relate to the restricted bite angle of the chelating ligands, i.e. O—Zn—O = 59.65 (5) and N—Zn—N = 76.50 (6)°, and the close approach of the non-coordinating carbonyl atom [Zn...O = 2.858 (2) Å]. In the crystal, molecules are consolidated into a three-dimensional architecture by C—H...O interactions
