Crystal structure of (E)-2-amino-4-methyl­sulfanyl-6-oxo-1-{[(thiophen-2-yl)­methyl­idene]­amino}-1,6-di­hydro­pyrimidine-5-carbo­nitrile

The title compound, C(11)H(9)N(5)OS(2), a 1-thio­phen-2-yl­methyl­ene­amino­pyrimidine derivative, displays an essentially planar C—NH(2) group. The conformation across the N=C bond linking the pyrimidine and thienyl groups is E. The pyrimidine and thienyl ring systems subtend an inter-planar angle of 42.72 (5)°. In the crystal, mol­ecules are linked by N–H⋯N(nitrile) and N–H⋯O=C hydrogen bonds, forming chains parallel to the b axis.
