“…Consequently, the bonding electron pair in the ah orbital becomes more and more localized at both cobalt atoms in going from Hg to Zn. This assumption is consistent with results of independent experiments [2]. In contrast, the s (M) orbital For the mercury complex qualitative observations of this photolysis had been made before [lo].…”

The electronic absorption spectra of the complexes [(OC),Co-'M"Co-'(CO),] with M = Zn, Cd, and Hg display an intense long-wavelength band which is assigned to the allowed X:u' --, Cg+ transition from a non-bonding u to an antibonding u orbital of the Co-M-Co moiety. This transition is shifted to higher energies and gains an increasing charge transfer (CT) contribution in changing M in the order M = Hg, Cd, and Zn. In a limiting description the u" + u* transition can be regarded as a metal to metal (MM) CT transition from Co-' to Mu. MMCT excitation induces a photoredox reaction: [(OC),Co-'-M"-Co-'(CO),] -+ MO + ]Cot(CO),]. The quantum yields are $a = 0.45 (hi, = 333 nm) for M = Hg and + = 0.03 (Ai, = 313 nm) for Cd.
