6-Methyl-2,7-diphenyl-1,4-diazepan-5-one
Abstract
The title compound, C18H20N2O, crystallizes with two molecules in the asymmetric unit. The seven-membered ring in both molecules adopts a distorted chair conformation. The dihedral angles between the phenyl rings are 43.2 (1) and 54.7 (1)° in the two molecules. The crystal packing features N—H...O and weak N—H...π and C—H...π interactions.
