Rhenacarborane [1,1-(CO)2-1,1-I2-isonido-1,2,4-ReC2B8H10]–. Synthesis, Properties, and Molecular Structure

The reaction of a rhenium carborane complex [1,1,1-(CO)3-isonido-1,2,4-ReC2B8H10]– tmndH+ (1) with an equimolar amount of I2 in CH2Cl2 at room temperature for 1 h leads to the formation of complex [1,1-(CO)2-1,1-I2-isonido-1,2,4-ReC2B8H10]– tmndH+ (2). The structure of complex 2 was confirmed by the data of NMR, IR, and UV-Vis spectroscopy, elemental analysis, and X-ray diffraction. In addition, complexes (1) and (2) were studied by cyclic voltammetry.
