Conclusions
We have carried out a complete x-ray structural analysis of (CCH3)2B10H8(CH3)2, one of the products resulting from the methylation of aminated dianions of 1,2-dimethyl-o-carborane, and have shown that the compound with all methyl groups joined to the four neighboring vertices of the carborane ring is 1,2,3,6-tetramethyl-o-carborane.
