Ontology highlight
ABSTRACT: In the title compound, C10H20N4O3, the piperazine ring adopts a chair conformation. The mol-ecule adopts an E conformation across the C=N double bond, with the -OH group and the piperazine ring trans to one another. Further, the H atom of the hy-droxy group is directed away from the NH2 group. An intra-molecular N-H⋯O contact occurs involving the NH2 group and the oxime O atom. In the crystal, mol-ecules are linked via strong N-H⋯O and O-H⋯N hydrogen bonds with alternating R2(2)(6) and C(9) motifs into tetra-meric units forming R4(4)(28) motifs.
