Abstract:	The superoxo complex [Co(CN)₅O₂]^3- was found to act as a reducing agent towards quinones. One-electron reduction took place with $o$ -quinones whereas two-electrons reduction with $p$ -quinones. 3,5-Di- $t$ -butyl- $o$ -benzoquinone gave the corresponding semiquinone Co(III) complex quantitatively.
