Decaborane

Decaborane, also called decaborane(14), is the borane with the chemical formula B₁₀H₁₄. This white crystalline compound is one of the principal boron hydride clusters, both as a reference structure and as a precursor to other boron hydrides. It is toxic and volatile, with a chocolate-like odor.

Handling properties and structure

B₁₀H₁₄ possesses a strong characteristic odor, sometimes described as musty or intensely bitter, chocolate-like that is unique to boranes. The physical characteristics of decaborane(14) resemble those of the organic compounds, such as naphthalene and anthracene, in that it can be sublimed under vacuum at moderate temperatures. Sublimation is the common method of purification. Like organic compounds, decaborane is highly flammable, but, like other boron hydrides, it burns with a bright green flame. It is not sensitive to moist air, although it hydrolyzes in boiling water, releasing hydrogen and giving a solution of boric acid. It is soluble in cold water as well as a variety of non-polar and moderately polar solvents.
