The title compound, [Cd2Cl4(C18H14N4O)2], was obtained from the reaction of Cd(NO3)2·4H2O with 2-phenyl-pyridine-keton picolinoyl hydrazone and sodium chloride. Each Cd(2+) cation is coordinated by two N atoms and one O atom of the tridentate ligand and three chloride anions, forming a distorted CdNOCl3 octahedron. Each pair of adjacent metal cations is linked by two bridging chloride ligands, resulting in a dinuclear complex unit. The mol-ecular conformation is stabilized by intra-molecular N-H⋯N and C-H⋯O hydrogen bonds. In the crystal, mol-ecules are linked by nonclassical C-H⋯O and C-H⋯Cl hydrogen bonds into a three-dimensional network. In addition, π-π stacking inter-actions [centroid-centroid distances = 3.777 (2) and 3.631 (2) Å] contribute to the stabilization of the crystal packing.
标题化合物[Cd₂Cl₄(C₁₈H₁₄N₄O)₂]是由Cd(NO₃)₂·4H₂O与2-苯基吡啶酮吡啶甲酰腙和氯化钠反应制得的。每个Cd(2+)阳离子由三齿配体的两个N原子和一个O原子以及三个氯离子配位，形成一个扭曲的CdNOCl₃八面体。每对相邻的金属阳离子通过两个桥联氯配体相连，形成一个双核配合物单元。分子构象通过分子内的N-H⋯N和C-H⋯O氢键得以稳定。在晶体中，分子通过非经典的C-H⋯O和C-H⋯Cl氢键连接成三维网络。此外，π-π堆积相互作用[质心-质心距离 = 3.777 (2) 和3.631 (2) Å]有助于晶体堆积的稳定。
