(E)-2-(2-Hydroxy-5-iodobenzylidene)hydrazinecarboxamide

Abstract

In the title molecule, C8H8IN3O2, there is an intramolecular O—H...N hydrogen bond between the hydroxy group and the imine N atom, which generates an S(6) ring. In the crystal, the carbonyl O atom accepts two different N—H...O hydrogen bonds, which connect molecules with two R22(8) motifs.
