Crystal structure, Hirshfeld surface analysis and geometry optimization of 2-hydroxyimino-N-[1-(pyrazin-2-yl)ethylidene]propanohydrazide

Abstract

In the molecule of the title compound, C9H11N5O2, the oxime and hydrazide groups are situated in a cis-position in relation to the C—C bond linking the two functional groups. The CH3C(=NOH)C(O)NH fragment deviates from planarity because of a twist between the oxime and amide groups. In the crystal, molecules are linked by O—H...O hydrogen bonds, forming zigzag chains in the [013] and [0\overline{1}3] directions.
