2,6-Dimethyl-1,4-benzopuinone 4-Monooxime

Abstract

Molecules of the title compound, C<inf>8</inf>H<inf>9</inf>NO<inf>2</inf>, are linked into sheets by a combination of C - H⋯N, O - H⋯N and O-H⋯O hydrogen bonds and C-H⋯π interactions. The hydrogen bonds are arranged as described by the graph-set ring notations R<inf>2</inf> 2(7) and R<inf>2</inf>2(5), and a C8 chain motif. There are two planar symmetry-independent molecules in the asymmetric unit, with a dihedral angle of 19.24 (5)° between their least-squares mean planes. © 2005 International Union of Crystallography.
