Crystal structure and Hirshfeld surface analysis of N-[(Z)-(2-hydroxyphenyl)methylidene]aniline N-oxide

Abstract

The conformation of the title compound, C13H11NO2, is partially determined by a strong, intramolecular O—H...O hydrogen bond. The crystal packing consists of strongly corrugated layers parallel to the ac plane and associated through C—H...π(ring) interactions. A Hirshfeld surface analysis of the crystal structure indicates that the most significant contributions to the crystal packing are from H...H (44.1%), C...H/H...C (29.4%) and O...H/H...O (17.3%) contacts.
