In the title compound. C19H36N3+·I−. the orientation of the cyclohexyl rings around the planar (sum of N—C—N angles = 360°) CN3+ unit produces steric hindrance around the N—H groups. As a consequence of this particular orientation of the tricyclohexylguanidinium cation (hereafter denoted CHGH+). https://www.itsmajorlook.com/
