Hexaborane, also called hexaborane(10) to distinguish it from hexaborane(12) (B₆H₁₂), is a boron hydride cluster with the formula B₆H₁₀. It is a colorless liquid that is unstable in air.^[1]

Structure

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 C_s.^[3]

Preparation and reactions

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]

K[BrB₅H₇] + 1/2 B₂H₆ → KBr + B₆H₁₀

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
