5,6,7,8-Tetrahydro-[1,2,4]triazolo[5,1-b]quinazolin-9(4H)-one

5,6,7,8-Tetrahydro-[1,2,4]triazolo[5,1-b]quinazolin-9(4H)-one

The triazole ring in the title molecule, C9H10N4O, is not quite coplanar with the six-membered ring to which it is fused, the dihedral angle between the two least-squares planes being 2.52 (6)°. In the crystal, a layered structure is formed by N—H...N and C—H...O hydrogen bonds plus slipped π-stacki...
