Crystal structure of 2-hy-droxy-2-phenyl-aceto-phenone oxime.

The title compound [systematic name: 2-(N-hy-droxy-imino)-1,2-di-phenyl-ethanol], C14H13NO2, consists of hy-droxy phenyl-aceto-phenone and oxime units, in which the phenyl rings are oriented at a dihedral angle of 80.54 (7)°. In the crystal, inter-molecular O-HOxm⋯NOxm, O-HHydr⋯OHydr, O-H'Hydr⋯OHydr and O-HOxm⋯OHydr hydrogen bonds link the mol-ecules into infinite chains along the c-axis direction. π-π contacts between inversion-related of the phenyl ring adjacent to the oxime group have a centroid-centroid separation of 3.904 (3) Å and a weak C-H⋯π(ring) inter-action is also observed. A Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (58.4%) and H⋯C/C⋯H (26.4%) contacts. Hydrogen bonding and van der Waals contacts are the dominant inter-actions in the crystal packing.
