Abstract

The title compound, C17H18N2O3, is constructed from a benzodiazepine ring system linked to a pendant dihydropyran ring, where the benzene and pendant dihydropyran rings are oriented at a dihedral angle of 15.14 (4)°. Intramolecular N—HDiazp...ODhydpand C—HDiazp...ODhydp(Diazp = diazepine and Dhydp = dihydropyran) hydrogen bonds link the seven-membered diazepine ring to the pendant dihydropyran ring, enclosingS(6) ring motifs. In the crystal, N—HDiazp...ODhydphydrogen bonds link the molecules into infinite chains along [10\overline{1}]. These chains are further linkedviaC—HBnz...ODhydp, C—HDhydp...ODhydpand C—HMth...ODhydp(Bnz = benzene and Mth = methyl) hydrogen bonds, forming a three-dimensional network. The observed weak C—HDiazp... π interaction may further stabilize the structure. Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H...H (51.1%), H...C/C...H (25.3%) and H...O/O...H (20.3%) interactions. Hydrogen bonding and van der Waals interactions are the dominant interactions in the crystal packing.
