Crystal structure of 3-amino-2-propylquinazolin-4(3H)-one

Abstract

In the title molecule, C11H13N3O, the propyl group is almost perpendicular to the quinazolin-4(3H)-one mean plane, making a dihedral angle of 88.98 (9)°. In the crystal, molecules related by an inversion centre are paired via π-π overlap, indicated by the short distances of 3.616 (5) and 3.619 (5) Å between the centroids of the aromatic rings of neighbouring molecules. Intermolecular N-H···N and N-H···O hydrogen bonds form R66(30) rings and C(5) chains, respectively, generating a three-dimensional network. Weak C-H···O interactions are also observed.
