| Abstract: | Hydrazones exhibit a versatile chemistry and are of interest for their potential use as functional molecular systems capable of undergoing reversible changes of configuration, i.e. E/Z isomerization. The title compound, C12H12N4O, has an E configuration with respect to the hydrazone C=N bond. The crystal packing is formed by N—H...N and O—H...N hydrogen bonds that give a two‐dimensional layer structure and C—H...C interactions associated with layer stacking to produce the three‐dimensional supramolecular structure. These intermolecular interactions were analyzed and quantified by the Hirshfeld surface method and the two‐dimensional supramolecular arrangement was topologically simplified as a hcb network. |
