Evidence for the heterolytic fission of H2 by cobalt cyanide complexes
Abstract
Summary The relative intensities of the Co–H/D stretching vibrations in the precipitated products show that the reaction of H2 with [COII5]3–(L = CN–) in D2O produces equal amounts of [CoIIIL5H]3– and [CoIIIL5D]3– which, taken together with kinetic and electrochemical data, indicates that H2 reacts with a binuclear [CO2L10]6– ion by heterolytic fission.
