A quinazolinthione, CHNOS, was synthesized by the condensation reaction of 6,7,8,9-tetra-hydro-11-pyrido[2,1-]quinazolin-11-thione with furfural. The mol-ecule crystallizes in the monoclinic system ( space group) and has an configuration with respect to the exocyclic C=C bond. In the crystal, mol-ecules are linked through C-H⋯π(furan) inter-actions, forming zigzag chains propagating along the [001] direction.
