摘要：

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-CB11H10](-) [X = F (1), Cl (2), Br (3), OH (4)]. These anions were isolated as [Et4N](+) 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-CB11H10]center dot(CH3)(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. ((C) Wiley-VCH Verlag GmbH & Co.
