چکیده
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.
