4-[(E)-({4-[Bis(2-hydroxyethyl)amino]phenyl}imino)methyl]phenol

Abstract

In the title compound, C17H20N2O3, the amino N atom is in a planar environment (sum of angles = 360.0°). All hydroxy H atoms are involved in hydrogen bonding. In the crystal structure, two O—H...O and an O—H...Nimino hydrogen bond result in the formation of a three-dimensional network. The latter hydrogen bonding causes distortion of the planarity of the 4-HO–C6H4–CH=N–C6H4– fragment by rotation around the =N—CPh bond. The crystal studied was a non-merohedral twin [refined BASF parameter for the major component = 0.5293 (7)].
