Di­chlorido­{2-[(E)-phen­yl(pyridin-2-yl-κN)methyl­idene]-N-phenyl­hydra­zine­carboxamide-κ²N²,O}copper(II)

The title compound, [CuCl₂(C₁₉H₁₆N₄O)], contains a Cu^II atom N,N′,O-chelated by a neutral N-phenyl­hy­dra­zine­car­box­amide ligand and additionally coordinated by two Cl atoms, resulting in a distorted square-pyramidal geometry. The ligating atoms in the basal square plane of the complex comprise the azomethine N, the pyridine N, the amide O and one of the Cl atoms, whereas the other Cl atom occupies an apical position. The apical Cl atoms in adjacent layers function as hydrogen-bond acceptors to both NH groups. Intermolecular C—H...Cl and C—H...O interactions are also observed.

N′-[(E)-2-Fluoro­benzyl­idene]benzo­hydrazide

The asymmetric unit of the title compound, C₁₄H₁₁FN₂O, contains two independent mol­ecules, both of which adopt the E conformation with respect to the azomethine C=N bond. The mol­ecules are non-planar, with dihedral angles of 26.92 (12) and 11.36 (11)° between the benzene and phenyl rings. In the crystal, mol­ecules are linked through N—H...O=C and N—H...N hydrogen bonds into chains along [101]. C—H...O contacts link these chains into layers parallel to (001). The three-dimensional crystal packing is stabilized by π–π inter­actions, the shortest separation between the centroids of benzene rings being 3.884 (1) Å.
