초록
The title compound, [1-(CH3)(3)NCH2-1,2-C2B10H11](+)center dot I- or C6H22B10N+center dot I-, was obtained by the reaction of (1,2-dicarba-closo-dodecaboranyl) dimethylmethanamine with methyl iodide. The asymmetric unit contains two iodide anions and two (o-carboranyl)tetramethylammonium cations. The bond lengths and angles in the carborane cage are within normal ranges, but the N-C-methylene-C-cage angle is very large [120.2 (2)degrees] because of repulsion between the carborane and tetramethylammonium units. In the crystal, ions are linked through C-H center dot center dot center dot I hydrogen bonds.
