The salts ^+- and ^+- show long-wavelength absorptions at λ_max 749 nm and 665 nm.These bands are assigned to metal to metal charge transfer (MMCT) transitions from Mn^-I to Co^III and Cr^I.Upon MMCT excitation the former ion pair is converted to Co(C5H5)2 and Mn2(CO)10.The latter ion pair undergoes an analogous redox reaction as a thermal process.The thermal and the light-induced electron transfer are explained on the basis of the Hush model.
