Abstract
In the title unsymmetrical tertiary amine, C24H33NO2, which arose from the ring-opening reaction of a dihydrobenzoxazine, two 2,4-dimethylphenol moieties are linked by a 6,6'-(cyclohexylazanediyl)-bis(methylene) bridge: the dihedral angle between the dimethylphenol rings is 72.45 (7)degrees. The cyclohexyl ring adopts a chair conformation with the exocyclic C-N bond in an equatorial orientation. One of the phenol OH groups forms an intramolecular O-H center dot center dot center dot N hydrogen bond, generating an S(6) ring, and a short intramolecular C-H center dot center dot center dot O contact is also present. In the crystal, O-H center dot center dot center dot O hydrogen bonds link the molecules into C(10) chains propagating along the [100] direction. The Hirshfeld surface analysis of the title compound confirms the presence of these intra- and intermolecular interactions. The corresponding fingerprint plots indicate that the most significant contacts in the crystal packing are H center dot center dot center dot H (76.4%), H center dot center dot center dot C/C center dot center dot center dot H (16.3%), and H center dot center dot center dot O/O center dot center dot center dot H (7.2%).
