Hexaborane(12)
Hexaborane(12) is an inorganic compound with the formula BH. It is an obscure member of the boranes. It is a colorless liquid that, like most boron hydrides, is readily hydrolyzed and flammable. The molecular structure conforms to C symmetry group. With the formula BH, it is classified as an "arachno-"cluster. As such the boron positions match six of the boron positions in the closo-BH. Preparation. It is typically prepared by the cluster expansion method from BH, the conjugate base of pentaborane(9):
