Protiomethonium dication

Multiply Protonated Methane Ions and Their Analogs. In addition to the involvement in a single 2e-3c bond formation, carbon is also capable of simultaneously participating in two 2e-3c bonds in some carbodications. Diproto-nated methane (protiomethonium dication, CH62+) is the parent of such carbodications.
