Abstract
The mol-ecule of the title compound, CHNO, exhibits crystallographically imposed twofold rotational symmetry, with a dihedral angle of 66.0 (2)° between the planes of the two central benzene rings bounded to the central oxygen atom. The dihedral angle between the planes of the central benzene ring and the terminal phenol ring is 4.9 (2)°. Each half of the mol-ecule exhibits an imine configuration. An intra-molecular O-H⋯N hydrogen bond is present. In the crystal, the mol-ecules are linked into layers parallel to the plane C-H⋯O hydrogen bonds. The crystal studied was refined as a two-component pseudomerohedral twin.
摘要
标题化合物CHNO的分子具有晶体学上的二重旋转对称性，两个与中心氧原子相连的中心苯环平面之间的二面角为66.0 (2)°。中心苯环平面与末端酚环平面之间的二面角为4.9 (2)°。分子的每一半都呈现亚胺构型。存在分子内O-H⋯N氢键。在晶体中，分子通过C-H⋯O氢键连接成平行于平面的层。所研究的晶体被精修为二组分假单形孪晶。
