1-{[(2,3-Dihydro-1H-inden-2-yl)oxy]-methyl}quinazoline-2,4(1H,3H)-dione

Abstract

In the title molecule, C18H16N2O 3, the five-membered ring has an envelope conformation, with the substituted C atom deviating by 0.342 (4) Å from the mean plane P calculated for the remainder of the non-H atoms of the 2,3-dihydro-1H-indene fragment. The mean planes of quinazoline-2,4(1H,3H)-dione fragment and P form a dihedral angle of 59.08 (4)°. In the crystal, pairs of N - H⋯O hydrogen bonds link molecules into inversion dimers, and weak C - H⋯O hydrogen bonds and π-π interactions between the benzene rings of the quinazoline ring systems [centroid-centroid distance = 3.538 (3) Å] further consolidate the packing.
