The compound consists of hydroxy phenylacetophenone and oxime units, with molecules linked into infinite chains through hydrogen bonds along the c-axis direction. Hydrogen bonding and van der Waals contacts play dominant roles in the crystal packing.
The title compound [systematic name: 2-(N-hydroxyimino)-1,2-diphenyl-ethanol], C14H13NO2, consists of hydroxy phenylacetophenone and oxime units, in which the phenyl rings are oriented at a dihedral angle of 80.54 (7)degrees. In the crystal, intermolecular O-H-Oxm center dot center dot center dot N-Oxm, O-H-Hydr center dot center dot center dot O-Hydr, O-H-Hydr'center dot center dot center dot O-Hydr and O-H-Oxm center dot center dot center dot O-Hydr hydrogen bonds link the molecules into infinite chains along the c-axis direction. pi-pi contacts between inversion-related of the phenyl ring adjacent to the oxime group have a centroid-centroid separation of 3.904 (3) angstrom and a weak C-H center dot center dot center dot pi(ring) interaction is also observed. A Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H center dot center dot center dot H (58.4%) and H center dot center dot center dot C/C center dot center dot center dot H (26.4%) contacts. Hydrogen bonding and van der Waals contacts are the dominant interactions in the crystal packing.
