Abstract
The asymmetric unit of the title compound, C6H16B10, contains one molecule that is close to possessing a non-crystallographic plane of mirror symmetry in the space group Pna21. The orientation of the molecules in the orthorhombic cell shows that the structure can not be described in the space group Pnma, which has the same systematic absence conditions. The long inner-cluster C—C distance of 1.510 (5) Å is typical for {1,2-Me2-closo-1,2-C2B10} derivatives.
