Decaborane, also known as B10H14 or icosahedral boron hydride, is a chemical compound composed of boron and hydrogen atoms. It is a borane cluster, meaning it consists of boron atoms arranged in a three-dimensional cluster with hydrogen atoms attached to the boron vertices. Decaborane has a unique and highly symmetrical icosahedral structure.

The molecular formula of decaborane is B10H14, which means it contains ten boron atoms and fourteen hydrogen atoms. The boron atoms form a dodecahedron with each boron atom bonded to two neighboring boron atoms and two hydrogen atoms.

Decaborane is a volatile and flammable compound, and its vapor is toxic, making it challenging to handle. Due to its high boron content and unique structure, decaborane has been studied for various applications, including as a rocket propellant and as a potential source of boron for neutron capture therapy in cancer treatment.

However, its use is limited due to its high reactivity and safety concerns associated with handling and storage. As with any highly reactive and potentially hazardous chemical, proper safety precautions and handling procedures should be followed when working with decaborane.
