Graphical Abstract
Reversible hypercloso – closo interconversion by means of simple redox chemistry: Two-electron reduction of hypercloso-[1-(η6-C6Me6)-1-RuB9H9] (1) gives the closo dianion 22−, which displays the bicapped square-antiprismatic structure expected for a closo cluster with 2n+2 skeletal electrons. The dianion 22− is quantitatively oxidized back to 1 by simple air oxidation.
