Definitive crystal structure of 1,1′-bis[1,2-dicarba-closo-dodecaborane(11)]

Abstract

In the title compound, C4H22B20, 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.
