In the title compound, C(19)H(36)N(3) (+)·I(-), the orientation of the cyclo-hexyl rings around the planar (sum of N-C-N angles = 360°) CN(3) (+) unit produces steric hindrance around the N-H groups. As a consequence of this particular orientation of the tricyclo-hexyl-guanidinium cation (hereafter denoted CHGH(+)), hydrogen bonding is restricted to classical N-H⋯I and non-clasical (cyclo-hex-yl)C-H⋯I hydrogen bonds. The propeller CHGH(+) cation and the oriented hydrogen-bonding interactions lead to a three-dimensional supra-molecular structure.
在标题化合物C(19)H(36)N(3) (+)·I(-)中，环己基环围绕平面型（N-C-N角之和 = 360°）的CN(3) (+)单元的取向在N-H基团周围产生空间位阻。由于三环己基胍阳离子（以下简称CHGH(+)）的这种特殊取向，氢键作用仅限于经典的N-H⋯I和非经典的（环己基）C-H⋯I氢键。螺旋桨状的CHGH(+)阳离子和定向的氢键相互作用导致了三维超分子结构。
