ABSTRACT
The mol-ecular and crystal structures of a benzoyl-hydrazine bearing an ether group, 4-[(4-methyl-benz-yl)-oxy]benzohydrazide, C15H16N2O2, (I), and of the corresponding N'-[(thio-phen-2-yl)-methyl-idene]- derivative, 4-[(4-methyl-benz-yl)-oxy]-N'-[(thio-phen-2-yl)-methyl-idene]benzohydrazide, C20H18N2O2S, (II), are described. The supra-molecular structures of both compounds are governed by N-Hâ¯N and N-Hâ¯O hydrogen-bonding inter-actions. The hydrazine compound (I) shows a crystal packing with a more complex hydrogen-bonding scheme because of the NH-NH2 entity, forming a di-periodic supra-molecular structure extending parallel to (100). Hydrazone mol-ecules in (II) are hydrogen-bonded through N-Hâ¯O inter-actions, giving rise to the formation of ribbons parallel to [010]. Mol-ecules of (I) and (II) show a different orientation of the carbohydrazide moiety likely to favor the crystal packing and thus hydrogen-bonding inter-actions.
