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], C(14)H(13)NO(2), 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-H(Oxm)⋯N(Oxm), O-H(Hydr)⋯O(Hydr), O-H'(Hydr)⋯O(Hydr) and O-H(Oxm)⋯O(Hydr) 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)†à 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.
