Abstract

1 min read

A twist is evident in the title compound, C21H21N3O2, the dihedral angle between the terminal six-membered rings being 29.46&#8197;(10)&#176;; the linked five- and six-membered rings are coplanar [1.30&#8197;(11)&#176;]. The carbonyl O atom accepts intramolecular hydrogen bonds from the adjacent hydroxy and amine groups. The three-dimensional crystal packing is achieved through C&#8212;H...&#960; interactions.
