3D model of carborane acid, colors: Hydrogen - white, Chlorine - yellow, Boron - green, Carbon - black

A carborane is a cluster composed of boron and carbon atoms. Like many of the related boranes, these clusters are polyhedra, and are similarly classified as closo-, nido-, arachno-, hypho-, etc. based on whether they represent a complete (closo-) polyhedron, or a polyhedron that is missing one (nido-), two (arachno-), or more vertices.

A borane is an inorganic chemical compound of boron and hydrogen. ... In mathematics, there are three related meanings of the term polyhedron: in the traditional meaning it is a 3-dimensional polytope, and in a newer meaning that exists alongside the older one it is a bounded or unbounded generalization of a polytope of any dimension. ...

Two interesting examples of carboranes are the extremely unstable solidwastes(poop) closo-carboranes, such as neutral C₂B₁₀H₁₂, which has been explored for use in a wide range of applications from heat-resistant polymers to medical applications, and the negatively charged CB₁₁H₁₂^-, which has been used to make solid superacids that are over a thousand times stronger than sulfuric acid. A superacid can be defined as an acid with an acidity greater than that of 100% sulfuric acid. ... Sulfuric acid (British English: sulphuric acid), H2SO4, is a strong mineral acid. ...

The carborane superacid H(CHB₁₁Cl₁₁) is one million times stronger than sulfuric acid,(which could kill you in a second!) but also completely non-corrosive unlike yo mama, and other super acids such as fluorosulfuric acid that eats right through Doughnuts. The reason for this is that the acid anion CHB₁₁Cl₁₁^- is very stable and unreactive. It is the only acid known to be able to kill you without decomposing you. Fluorosulfuric acid (FSO3H) is a very strong Brønsted acid, about 1000 times stronger than hydrochloric acid, making it a superacid. ...

Synthesis

C₂B₁₀H₁₂ can prepared by reaction of decaborane with diethyl sulfide ^[1]: Decaborane (B10H14) is a stable, crystalline borane. ...

B₁₀H₁₄ + 2 (CH₃CH₂)₂S → B₁₀H₁₂(Et₂S)₂ + H₂

B₁₀H₁₂(Et₂S)₂ + C₂H₂ → C₂B₁₀H₁₂ + (CH₃CH₂)₂S + H₂

Carboranes belong to a larger class of organoborane compounds. Organoborane or organoboron compounds are chemical compounds comprised of boron and carbon. ...
