Abstract: The title compound, C₂₇H₂₂N₂O₂, consists of two chemically equivalent halves. However, it displays no crystallographic symmetry, only an approximate local twofold symmetry (r.m.s. deviation = 0.15 Å between the two halves of the molecule) is observed. In the crystal, molecules are connected by two antiparallel classical N-HO hydrogen bonds, forming broad chains parallel to (10). A series of weak C-HN/O hydrogen bonds is also present.
