Untersuchungen an Polyhalogeniden. XI. Darstellung und Kristallstruktur des Diethylmethylphenylammoniumtriiodids,Et2MePhNI3

Studies on Polyhalides. 11 Preparation and Crystal Structure of Diethylmethylphenylammoniumtriiodide, Et₂MePhNI₃ Diethylmethylphenylammoniumtriiodide C₁₁H₁₈NI₃ crystallizes at room temperature monoclinically with a = 824.1(2) pm, b = 1 428.5(2) pm, c = 1 430.0(2) pm, β = 103.17(3)° and Z = 4. The crystal structure is build up from layers of the quarternary ammonium ions Et₂MePhN⁺ and of the triiodide ions I₃^?, which alternate with each other along 1 0 0]. The packing of these layers and of the groups within each layer seems to be particularly effective without forming noticeable short contact distances.
