چکیده
The title compound, [1-(CH(3))(3)NCH(2)-1,2-C(2)B(10)H(11)](+)·I(-) or C(6)H(22)B(10)N(+)·I(-), was obtained by the reaction of (1,2-dicarba-closo-dodeca-boran-yl)dimethyl-methanamine with methyl iodide. The asymmetric unit contains two iodide anions and two (o-carboran-yl)tetra-methyl-ammonium cations. The bond lengths and angles in the carborane cage are within normal ranges, but the N-C(methyl-ene)-C(cage) angle is very large [120.2 (2)°] because of repulsion between the carborane and tetra-methyl-ammonium units. In the crystal, ions are linked through C-H⋯I hydrogen bonds.

In the title compound, 1,2-(SCH3)2-1,2-closo-C2B10H10 or C4H16B10S2, the methylsulfanyl groups are bonded to the C atoms of the 1,2-dicarba-closo-dodecaborane cage. The Ccage-Ccage distance is 1.8033 (18) A and the S-Ccage-Ccage-S torsion angle is 1.07 (13) degrees. The Ccage-Ccage distance is compared with those in other 1,2-dicarba-closo-dodecaborane derivatives.
