Conclusions 1. The C13 NMR spectra were obtained for the isomeric diphenylcarboranes, the dianions of these carboranes, 1,2-dimethyl-o-carborane, its dianion, and also the monoanions. The dianions from the o- and m-carborane are identical but the dianion from the p-carborane differs from them. The carbon nuclei of the carborane polyhedron occupy equivalent positions. 2. The C13 NMR spectra were obtained for the dianion from 1,2-diphenyl-o-carborane in THF at 0, −30, and −50°. There are no changes in the dianion's structure in this temperature rangs. 3. The monoanions, obtained from the isomeric diphenylcarboranes, are identical. The carbon nuclei of the carborane fragment and the phenyl rings in them have a nonequivalent position.
