Crystal structure and Hirshfeld surface analysis of (E)-4-amino-N′-[1-(4-methylphenyl)ethylidene]benzohydrazide

Abstract

The structure of the title Schiff base, C16H17N3O, displays a trans configuration with respect to the C=N double bond, with a dihedral angle of 14.98 (9)° between the benzene rings. In the crystal, molecules are linked by N—H...O and C—H...O hydrogen-bonding interactions, giving sheets extending across the (001) plane. Hirshfeld surface analysis gave fingerprint plots showing enrichment ratios for H...H, O...H, N...H and C...H contacts compared to C...C, N...N and C...N contacts, indicating a high propensity for H...H interactions to form in the crystal.
