(9E)-9-Benzyl­idene-2-methyl­sulfanyl-5-phenyl-6,7,8,9-tetra­hydro­pyrim­ido[4,5-b]quinolin-4(3H)-one: a hydrogen-bonded R22(8) dimer

Abstract: In the mol­ecule of the title compound, C25H21N3OS, which was prepared by mild oxidation of the corresponding 5,6,7,8,9,10-hexa­hydro analogue, the fused carbocyclic ring adopts an envelope conformation. Pairs of mol­ecules are linked into cyclic centrosymmetric dimers by pairs of inversion-related N-H...O hydrogen bonds.

CCDC reference: 970789

Formula: C25H21N3OS

Keywords: crystal structure; hydrogen-bonded dimer; tetra­hydro­pyrimidin-4(3H)-one; biological activity.
