4,4,6-Trimethyl-1-(3-methylphenyl)-3,4-dihydropyrimidine-2(1H)-thione

Abstract

The asymmetric unit of the title compound, C14H 18N2S, contains two independent and conformationally similar mol-ecules, which form cyclic dimers via inter-molecular hydrogen bonds of the type N - H⋯S [graph set R 22(8)]. The structure is iso-morphous with that of one of the polymorphs of 4,4,6-tri-methyl-1-phenyl-3,4-dihydro-pyrimidine-2(1H)-thione [Yam-in et al. (2005). Acta Cryst. E61, o55-o57].
