Crystal structure of 3-(9H-carbazol-9-yl)-N′-[(E)-4-chlorobenzylidene]propanohydrazide

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 chlorophenyl ring. In the crystal, neighbouring molecules are linked into centrosymmetric R22(8) dimers by pairs of N—H...O interactions and into a three-dimensional network by C—H...π interactions. The dimers are arranged into layers parallel to (010).
