The Zn(II) 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 carboxyl-ate-O atoms derived from the monodentate and bidentate carboxyl-ate 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, mol-ecules are consolidated into a three-dimensional architecture by C-H⋯O inter-actions.
在标题化合物[Zn(C₂H₃O₂)₂(C₁₄H₁₃N₃)]中,Zn(II)原子由一个由螯合杂环配体的喹啉基和吡唑基-N原子定义的N₂O₃供体集以及来自单齿和双齿羧酸盐配体的三个羧酸盐-O原子配位。与理想的正方锥配位几何结构的偏差与螯合配体受限的咬角有关,即O-Zn-O = 59.65 (5)°和N-Zn-N = 76.50 (6)°,以及非配位羰基原子的近距离接近[Zn⋯O = 2.858 (2) Å]。在晶体中,分子通过C-H⋯O相互作用巩固成三维结构。
