carborane, Any of a class of organometallic compounds containing carbon, boron, and hydrogen. The general carborane chemical formula is C2BnHn + 2, in which n is an integer; carboranes with n ranging from 3 to 10 have been described. Carboranes can form three-centre bonds (one pair of electrons is shared between three atoms) and classical two-centre bonds (one pair of electrons is shared between two atoms). As a result, carboranes can form complex polyhedral structures that are based on networks of boron and carbon atoms. Carboranes are generally prepared by reaction of acetylene or acetylene derivatives with boron hydrides.
