Abstract

The asymmetric unit of the title compound, C(22)H(26)N(2)O, contains three crystallographically independent mol-ecules, in which the aromatic rings are oriented at dihedral angles of 21.74 (5), 27.59 (5) and 27.87 (5)°. Intra-molecular O-H⋯N hydrogen bonds result in the formation of planar six-membered rings, and these are nearly coplanar with the adjacent rings. In the crystal structure, π-π contacts between the benzene rings [centroid-centroid distances = 3.989 (2), 3.802 (1) and 3.882 (1) Å] may stabilize the structure.
