1-Methyl-5-(4-Methylbenzoyl)-4-(4-Methylphenyl)Pyrimidine-2(1H)-Thione

Abstract

The title compound, C20H18N2OS, contains three rings that are not coplanar. The benzene rings make dihedral angles of 31.37 (8) and 68.84 (5)° with the pyrimidine ring, while the dihedral angle between the two benzene rings is 76.70 (5)°. The structure is stabilized by inter-molecular C - H⋯O hydrogen bonds, resulting in the formation of mol-ecular chains along the [010] direction. © International Union of Crystallography 2007.
