Unsymmetrically Substituted Thioureas. 1,1-Dimethyl-3-o-tolylthiourea and 1,1-Diethyl-3-o-tolylthiourea

The two unsymmetrically substituted thiourea derivatives, 1,1-dimethyl-3-o-tolyl­thiourea, C₁₀H₁₄N₂S, and 1,1-diethyl-3-o-tolyl­thiourea, C₁₂H₁₈N₂S, both crystallize in the orthorhombic space group P2₁2₁2₁ and have the same type of crystal packing. In both structures, N—H...S hydrogen bonds link the molecules into chains along the b axis.
