The asymmetric unit of the title compound, C(6)H(16)B(10), contains one mol-ecule that is close to possessing a non-crystallographic plane of mirror symmetry in the space group Pna2(1). The orientation of the mol-ecules in the ortho-rhom-bic 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-Me(2)-closo-1,2-C(2)B(10)} derivatives.
标题化合物C(6)H(16)B(10)的不对称单元包含一个分子，在空间群Pna2(1)中该分子接近于具有非晶体学镜面。正交晶胞中分子的取向表明，该结构不能用具有相同系统消光条件的空间群Pnma来描述。1.510(5)Å的长簇内C-C距离对于{1,2-Me(2)-closo-1,2-C(2)B(10)}衍生物来说是典型的。
