Hexaborane, also called hexaborane(10) to distinguish it from hexaborane(12) (B6H12), is an inorganic compound with the formula B6H10. It is a colorless liquid that is unstable in air. [1]
Hexaborane(10) is classified as a nido-cluster. [2]: 152 The boron atoms define a pentagonal pyramid, with four bridging hydrogen atoms and six terminal ones. The point group of the molecule is Cs. [3]
A laboratory route begins with bromination of pentaborane(11) followed by deprotonation of the bromide to give [BrB5H7−. This anionic cluster is reduced with diborane to give the neutral product: [1]
It can also be generated by pyrolysis of pentaborane(11).
B6H10 can be deprotonated to give [B6H9− or protonated to give [B6H11+. [1] It can act as a Lewis base towards reactive borane radicals, forming various conjuncto-clusters. [2]: 162
