title: 2-Hydroxy-imino-N'-[1-(2-pyrid-yl)ethyl-idene]propanohydrazide.
abstract: The title compound, C(10)H(12)N(4)O(2), features an intra-molecular N-H⋯N hydrogen bond formed between the imine NH and oxime N atoms. The oxime group and the amide C=O bond are anti to each other. In the crystal, mol-ecules are connected by O-H⋯O hydrogen bonds into supra-molecular zigzag chains along the c axis.
