A study of the temperature dependence of the electronic spectra of alkyl cobaloximes.
The temperature dependence of the electronic spectra of the alkyl-pyridinatocobaloximes in benzene solution was found to be due to an equilibrium existing between two forms proposed to be inner-sphere and outer-sphere coordination compounds. Evidence is presented to rule out the possibilites of equilibria with pentacoordinated or dimeric forms, as well as a form with the cobalt out of the plane of the dimethylglyoxime.
