context_page_description: In organometallic chemistry, a dicarbollide is an anion of the formula [C₂B₉H₁₁]²⁻. Various isomers exist, but most common is 1,2-dicarbollide derived from ortho-carborane. These dianions function as ligands, related to the cyclopentadienyl anion. Substituted dicarbollides are also known such as [C₂B₉H₁₀]⁻ and [C₂R₂B₉H₉]²⁻.

Substituted dicarbollides are also known such as [C₂B₉H₁₀(pyridine)]⁻ (pyridine bonded to B) and [C₂R₂B₉H₉]²⁻ (R groups bonded to carbon).
