N-Hydroxy-N-o-tolylacetamide

In the mol-ecule of the title compound, C9H11NO2, the methyl C atom bonded to the ring and the N atom lie in the benzene ring plane. An intra-molecular O - H⋯O hydrogen bond results in the formation of a five-membered planar ring, which is oriented at a dihedral angle of 81.37 (3)°with respect to the benzene ring. In the crystal structure, inter-molecular O - H⋯O hydrogen bonds link the mol-ecules stacked along the b axis. There are also π-π inter-actions between benzene rings with a face-to-face stacking distance of 3.434 Å.
