In 1,1'-bis[1,7-dicarba-closo-dodecaborane(11)], the two {1,7-closo-C2B10H11} cages are linked across a centre of inversion. The position of the second non-linking cage C atom was established unambiguously by geometric and crystallographic methods and there is no evidence of C/B disorder.

In the title compound, the two {1,2-closo-C2B10H11} cages are linked across a centre of inversion with a C-C distance of 1.5339 (11) Å. By careful analysis of the structure, it is established that the non-linking cage C atom is equally disordered over cage vertices 2 and 3.
