Abstract
The asymmetric unit of the title compound, C16H20N2O2, consists of two independent molecules differing slightly in the conformations of the seven-membered rings and the butyl substituents, where the benzene rings are oriented at a dihedral angle of 34.56 (3)°. In the crystal, pairwise intermolecular C—H...O and complementary intramolecular C—H...O hydrogen bonds form twisted strips extending parallel to (012). These strips are connected into layers parallel to (111) by additional intermolecular C—H...O hydrogen bonds. The layers are further joined by C—H...π interactions. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H...H (65.5%), H...C/C...H (16.0%) and H...O/O...H (15.8%) interactions.
