2-[2-(3-Chlorophenyl)hydrazinylidene]-1,3-diphenylpropane-1,3-dione

Abstract

The molecular structure of the title compound, C21H15ClN2O2, features one strong intramolecular N—H...O resonance-assisted hydrogen bond (RAHB). In the crystal, molecules form inversion-related dimers via pairs of weak intermolecular N—H...O contacts. These dimers are further stabilized via three weak C—H...O contacts, developing the three-dimensional structure.
