Abstract

A quinazolinthione, C₁₇H₁₄N₂OS, was synthesized by the condensation reaction of 6,7,8,9-tetra-hydro-11H-pyrido[2,1-b]quinazolin-11-thione with furfural. The mol-ecule crystallizes in the monoclinic system (Cc space group) and has an E 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.

Keywords: E-configuration; crystal structure; quinazolinthione.
