Synthesis, crystal structure and Hirshfeld surface analysis of 3-ethyl-2-(methyl-sulfan-yl)-5,5-diphenyl-3-imidazol-4(5)-one (Thio-phenytoin analogue).

In the title mol-ecule, 3-ethyl-2-(methyl-sulfan-yl)-5,5-diphenyl-3-imidazol-4(5)-one, CHNOS, the two substituent phenyl rings are inclined of 59.50 (7) and 83.53 (8)° with respect to the plane of the five-membered ring. The -methyl group lies in this plane while the ethyl group is nearly perpendicular to it. In the crystal, weak C-H⋯O hydrogen bonds form inversion dimers, which pack conventional van der Waals contacts. A Hirshfeld surface analysis was performed, showing the predominance of H⋯H and C⋯H/H⋯C contacts.
