The crystallographic characterization of N-(2-hydroxybenzylideneamino)benzamide, C14 HI2 N2 O2, reveals quasi coplanarity of the whole molecular skeleton, localization of the double bonds in the central --C~N--N--C=~ chain, which has an E configuration with respect to the double bond of the hydrazone bridge, and an amide trans, s-cis configuration around the single N--N bond. The molecules are held together by hydrogen bonds linking them into layers along the [ 100] direction.
