Abstract Incomplexes of the type [(NC)2HgIIN CFeII(CN)5]4- which are formed in aqueous mixtures of Hg(CN)2 and [Fe(CN)6]4- both metals are weakly coupled. Optical metal to metal charge transfer (MMCT) excitation from FeII to HgIIleads to the reduction of HgII to Hg0 an the oxidation of [Fe(CN)6]4- to [Fe(CN)6]3-. In the complex [(NC)5CoI-HgII-CoI(CN)5]6- the m etals are strongly coupled by direct but polar metal metal bonds. MMCT (CoI ￫ HgII) excitation induces the photoredox reaction: [HgCo2(CN)10]6-￫Hg0 + 2[Co(CN)5]3-.

Abstract The polar metal-metal bond of [Ph3PAu1-Co-1(CO)4] was cleaved photochemically by metal to metal (Co-1 ￫ Au+1) charge transfer excitation. Metallic gold, Ph3P, and [Co2(CO)8] were formed as products.

The ion pair [Hg(cyclam)]2+[Co(CO)4]- displays a Co(–I) to Hg(II) metal-to-metal charge transfer (MMCT) band at 288 nm. Upon MMCT excitation the ion pair undergoes a photoconversion to [HgCO2(CO)8].
