Abstract
The title compound, 2-hydroxyimino-N-[1-(2-pyrazinyl)ethylidene]propanehydrazide, is a ligand able to form polynuclear metal complexes. The molecule is not planar due to a twist between the oxime and amide groups. In the crystal, molecules are linked by O—H⋯O hydrogen bonds into supramolecular chains.
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 [03] directions.
