A new eight-vertex arachno-dicarbaborane anion, [4,5-C2B6H11]

Abstract
The title anion is produced via selective degradation of the B(3,6) cage atoms within the structure of closo-1,2-C2B8H10 and the proposed geometry of this novel arachno-[4,5-C2B6H11] anion is based upon multinuclear and two-dimensional n.m.r. experiments.
