Bottom Line: 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.

Mentions: Mol­ecules of 1,1′-bis­[1,2-dicarba-closo-dodeca­borane(11)] are composed of two {1,2-closo-C2B10H11} cages (the contents of one asymmetric fraction of the unit cell), linked across a crystallographic inversion centre by the C1–C1A bond [1.5339 (11) Å; symmetry code: (A) −x, −y + 2, −z + 2] (Fig. 1 ▶). The two cages are essentially co-linear, with B12⋯C1—C1A = 175.14 (5)°.
