How to Overcome Coulomb Explosions in Labile Dications by Using the [B12Cl12]2- Dianion.

The dicationic homoleptic lithium–sulfur dioxide complex [Li2(SO2)8]2+ in [Li2(SO2)8][B12Cl12] has been characterized by X-ray diffraction; [Li2(SO2)8]2+ is stabilized in the solid state by the weakly-coordinating dianion [B12Cl12]2− and the high lattice enthalpy of the resulting dication–dianion salt.
