title: Crystal structure of 3-(9H-carbazol-9-yl)-N'-[(E)-4-chloro-benzyl-idene]propano-hydrazide.
abstract: In the title compound, C22H18ClN3O, the carbazole ring system is essentially planar (r.m.s deviation = 0.003 Å), and makes a dihedral angle of 9.01 (8)° with the plane of the chloro-phenyl ring. In the crystal, neighbouring mol-ecules are linked into centrosymmetric R 2 (2)(8) dimers by pairs of N-H⋯O inter-actions and into a three-dimensional network by C-H⋯π inter-actions. The dimers are arranged into layers parallel to (010).
