(2E)-N'-[(E)-Benzyl-idene]-3-phenyl-prop-2-enohydrazide from synchrotron radiation

Abstract

In the title compound, C(16)H(14)N(2)O, the dihedral angle between the phenyl rings is 25.48 (12)°. An E conformation is found for each of the imine [1.269 (3) Å] and ethyl-ene [1.313 (3) Å] bonds. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, leading to zigzag chains along [010]. Supra-molecular layers in the ab plane are formed, whereby the chains are linked by C-H⋯N and C-H⋯π inter-actions.
