title: Negatively charged metallacarborane redox couples with both members stable to air.
abstract: The metallacarborane [3,3'-Co(1,2-closo-C2B9H11)2](-) has been synthesized. This species allows the formation of redox couples in which both partners are negatively charged. The E1/2 potential can be tuned by adjusting the nature and number of substituents on B and C. The octaiodinated species [3,3'-Co(1,2-closo-C2B9H7I4)2](-) is the most favorable, as it is isolatable and stable in air. A DFT study on stability and redox potentials of complexes has been performed.
