Crystal structure of 3-amino-2-ethylquinazolin-4(3H)-one
Abstract
The molecule of the title compound, C10H11N3O, is planar, including the ethyl group, as indicated by the N—C—C—C torsion angle of 1.5 (2)°. In the crystal, inversion-related molecules are stacked along the a axis. Molecules are oriented head-to-tail and display π–π interactions with a centroid-to-centroid distance of 3.6664 (8) Å. N—H...O hydrogen bonds between molecules generate a `step' structure through formation of an R22(10) ring.
