Acta Crystallogr E Crystallogr Commun. 2022 Aug 12;78(Pt 9):900-904. doi: 10.1107/S2056989022007927. eCollection 2022 Sep 1.

Abstract

In the mol-ecule 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, mol-ecules are linked by O-H⋯O hydrogen bonds, forming zigzag chains in the [013] and [03] directions.

Keywords: Schiff base; crystal structure; hydrazide; hydrazone; oxime; polynucleative ligand.
