Abstract
Crystal structures of two symmetrically substituted thiourea derivativ es, 1,3-dibenzylthiourea, C15H16N2S (DBTU), and 1,3-dicyclohexylthiour ea, C13H24N2S (DCHTU), are reported. One of the cyclohexane rings in D CHTU is disordered adopting two orientations separated by an angle of 44.6(2)degrees. In both structures centrosymmetrically related molecul es 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 bo th DBTU and DCHTU.
