inorganic compound In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemist ...
with the formula B6H12. 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 C2
symmetry group In group theory, the symmetry group of a geometric object is the group of all transformations under which the object is invariant, endowed with the group operation of composition. Such a transformation is an invertible mapping of the ambient ...
. With the formula BnHn+6, it is classified as an ''arachno-''cluster. As such the boron positions match six of the boron positions in the closo-B8H.


Preparation

It is typically prepared by the cluster expansion method from B5H, the conjugate base of pentaborane(9): p.172. :LiB5H8 + 1/2 B2H6 → LiB6H11 :LiB6H11 + HCl → B6H12 + LiCl
