Abstract

In the title compound, C(17)H(20)N(2)O(3), the amino N atom is in a planar environment (sum of angles = 360.0°). All hy-droxy H atoms are involved in hydrogen bonding. In the crystal structure, two O-H⋯O and an O-H⋯N(imino) hydrogen bond result in the formation of a three-dimensional network. The latter hydrogen bonding causes distortion of the planarity of the 4-HO-C(6)H(4)-CH=N-C(6)H(4)- fragment by rotation around the =N-C(Ph) bond. The crystal studied was a non-merohedral twin [refined BASF parameter for the major component = 0.5293 (7)].
