title: Crystal structure of 1,3-di-cyclo-hexyl-1-[3-(pyren-1-yl)prop-anoyl]urea.
abstract: In the title compound, C33H38N2O2, each of the cyclo-hexyl 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 mol-ecules are linked by a pair of N-H⋯O inter-actions, generating an inversion dimer. The dimers are inter-connected by C-H⋯O hydrogen bonds into a supra-molecular chain along the a-axis direction.
