(E,E)-N?-{4-[(2-Benzoylhydrazin-1-yl-idene)methyl]benzylidene} benzo-hydrazide

Abstract

In the title compound, C22H18N4O 2, the molecules lie across an inversion centre. The dihedral angle between the mean planes of the central and terminal benzene rings is 66.03 (2)°. The molecule displays trans and anti conformations about the C=N and N - N bonds, respectively. In the crystal, N - H?O hydrogen bonds, with the O atoms of C=O groups acting as acceptors, link the molecules into a chain along [101]. © Karimian et al. 2012.
