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

ABSTRACT: 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-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. ?-? 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??(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.
