title: 9-Ethynyl-1,2-dimethyl-1,2-dicarba-closo-dodeca-borane (1,2-Me(2)-9-HC C-closo-1,2-C(2)B(10)H(9)).
abstract: 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.
