 Carborane

A borane-derived cluster containing skeletal carbon vertices. In a simple neutral count, a CH vertex contributes three skeletal electrons while BH contributes two.

Carborane refers to a class of complex chemical compounds that consist of boron, carbon, and hydrogen. They are characterized by their unique three-dimensional structures that include clusters of boron and carbon atoms. One of the most notable types of carboranes is **decaborane** (C2B10H12), which contains a cluster of ten boron atoms and two carbon atoms, along with hydrogen atoms.
