Crystal structure of 1,3-dicyclohexyl-1-[3-(pyren-1-yl)propanoyl]urea

In the title compound, C33H38N2O2, each of the cyclohexyl rings adopts a chair conformation. The two planes involving carbonyl groups, C—(C=O)—N and N—(C=O)—N, are oriented at a dihedral angle of 62.28 (10)°. In the crystal, two neighboring molecules are linked by a pair of N—H...O interactions, generating an inversion dimer. The dimers are interconnected by C—H...O hydrogen bonds into a supramolecular chain along the a-axis direction.
