✦ Synopsis

The mononuclear q l-dioxygen complex [CO(CN),O,]~-(A) decomposes in aqueous solution to the hydroxocomplex [Co(CN),OHI3-(B) and the hydroperoxo complex [Co(CN),O0Hl3-(C). The mechanism involves partial dissociation of A to give [CO(CN),]~-(E) which binds with unreacted A to give the q':ql-peroxo complex [(CN),COO,CO(CN),]~-(F) which is hydrolysed to B and C. The mechanism is supported by the effects of pH, dioxygen concentration, and ionic strength on the rate of decomposition, and by the trapping of oxidation products of E and F. Complex A reacts readily with reducing agents to give directly the hydroperoxo complex C.

## Abstract Kinetic studies of solvent structure effects and solute–solvent interactions on the solvolysis of [Co(NH~3~)~5~Cl]^2+^ complex ion have been investigated spectrophotometrically in binary aqueous mixtures. Three cosolvents were used (acetonitrile, dimethylsulfoxide, and urea) over a wide
