Crystal structure of ethyl 6-methyl-2-sulfanyl­idene-4-(thio­phen-2-yl)-1,2,3,4-tetra­hydro­pyrimidine-5-carboxyl­ate

In the title compound, C(12)H(14)N(2)O(2)S(2), the di­hydro­pyrimidine ring adopts a sofa conformation, with the C atom bearing the thienyl ring lying above the plane of the five remaining approximately coplanar (r.m.s. deviation = 0.0405 Å) atoms of the ring. The dihedral angle between the five near coplanar atoms of the ring and the thienyl ring is 89.78 (11)°. In the crystal, mol­ecules are linked into a supra­molecular chain along [100] via N—H⋯O(carbon­yl) hydrogen bonds. Inversion-related chains are linked into double chains via N—H⋯S(thione) hydrogen bonds. The three-dimensional architecture also features meth­yl–thienyl C—H⋯π inter­actions.
