1,3-Dibenzylthiourea and 1,3-Dicyclohexylthiourea

Crystal structures of two symmetrically substituted thiourea derivatives, 1,3-dibenzylthiourea, C₁₅H₁₆N₂S (DBTU) and 1,3-dicyclohexylthiourea, C₁₃H₂₄N₂S (DCHTU) are reported. One of the cyclohexane rings in DCHTU is disordered adopting two orientations separated by an angle of 44.6 (2)°. In both structures centrosymmetrically related molecules are linked by N-H...S hydrogen bonds to form dimers and weak N-H...S bonds connecting glide-related molecules are also observed in both DBTU and DCHTU.
