Trimethylsulfonium 1-amino-6-fluoro-2,3,4,5,7,8,9,10,11,12-decaiodo-1-carba-closo-dodecaborate

M. Finze and G. J. Reiss

Abstract: In the asymmetric unit of the title salt, C₃H₉S⁺·CH₂B₁₁FI₁₀N^- or (CH₃)₃S[1-H₂N-6-F-closo-1-CB₁₁I₁₀], both ions lie in general positions. The anion is perfectly ordered and so the positions of the C-NH₂ vertex and the fluorine substituent are clearly assigned. The relatively short C-N bond length may be interpreted in terms of a very electron deficient {closo-1-CB₁₁} cluster.
