Abstract: Time-resolved infrared spectroscopy was used to probe the photochemistry of three (μ2-alkyne)Co2(CO)6 complexes. The data indicate the formation of a triplet diradical species, with lifetimes in the range 38−71 ps. Theoretical calculations support these experimental findings. No evidence for the CO loss species, (μ2-alkyne)Co2(CO)5, was observed, and this is rationalized by the low quantum yield for this process at the excitation wavelengths used.
