Abstract
Selective monoiodination of a series of carba‐closo‐dodecaborates with a halogen atom or a hydroxy substituent bonded to the antipodal boron atom resulted in salts of the novel anions [7‐I‐12‐X‐closo‐CB~11~H~10~]^–^ [X = F (1), Cl (2), Br (3), OH (4)]. These anions were isolated as [Et~4~N]^+^ salts and converted into the Cs^+^ salts. The novel compounds were studied by multi NMR spectroscopy, mass spectrometry (MALDI), and elemental analysis. The solid‐state structure of Cs[7‐I‐12‐HO‐closo‐CB~11~H~10~]·(CH~3~)~2~CO was determined by single‐crystal X‐ray diffraction. The assignment of the NMR spectroscopic data and the discussion of structural properties was supported by the results of the DFT calculations. (© Wiley‐VCH Verlag GmbH & Co.
