N,N′,N′′-Tricyclohexylguanidinium iodide
Abstract
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+), hydrogen bonding is restricted to classical N—H...I and non-clasical (cyclohexyl)C—H...I hydrogen bonds. The propeller CHGH+ cation and the oriented hydrogen-bonding interactions lead to a three-dimensional supramolecular structure.
