1,1-Diethyl-3-(4-methylbenzoyl)thiourea

The title compound, C₁₃H₁₈N₂OS, crystallizes as NH tautomer. The C5-C8(O)-N system tends to be coplanar with the phenyl ring [C4-C5-C8-O = 8.7 (4)°] because of some [pi]-conjugation along the O-C8-C(Ph) system [C5-C8 = 1.448 (4) Å] and the O...H4 = 2.49 Å attractive interaction. The molecules in the crystal are held together by van der Waals forces and an intermolecular N-H...O hydrogen bond.
