In the title asymmetric di-cyclo-hexyl-phenyl-guanidine, C25H41N3, the central guanidine C atom deviates by only 0.004 (2) Å from the central plane defined by the three N atoms. The benzene and the cyclo-hexyl rings are rotated out of the central plane of the N3C unit by 85.63 (12)° (benzene) and 51.52 (9) and 49.37 (12)° (cyclohexyl). The crystal packing features only by van der Waals inter-actions.
