N,N'-Dicyclohexylurea

The title molecule, C₁₃H₂₄N₂O, possesses twofold symmetry, with the C=O group lying on a crystallographic twofold axis in the unit cell. The cyclohexane rings adopt a chair conformation. Successive molecules along the twofold axis are related by the short b translation and interact through two identical diad-related N-H...O hydrogen bonds [2.962 (5) Å] in which the oxygen atom lying on the 2-fold axis acts as a common acceptor for the diad-related amino protons.
