Two-color resonance photoionization spectrum of nickelocene in a supersonic jet

Ferrocene/ferrocenium, cobaltocene/cobaltocenium and nickelocene/nickelocenium: from gas phase ionization energy to one-electron reduction potential in solvated medium

“…6.320 (F12a) and 6.321 (F12b) eV, after including the CV (0.007 eV), SR (À0.077 eV), SO (À0.001 eV) and ZPVE (0.024 eV), and they both are in excellent agreement with a value of 6.29 AE 0.015 eV 30 determined in a multiphoton ionization experiment, but significantly higher than another experimental value of 6.138 AE 0.012 eV, 31 measured using two-color resonance photoionization techniques. Another experimental IE(Cp 2 Ni) value of 6.24 AE 0.07 eV is obtained after applying the free energy contribution and temperature correction (0.003 eV) to a 350 K IE(Cp 2 Ni) value of 6.24 AE 0.07 eV (143.8 AE 1.5 kcal mol À1 ).…”

“…Obtained by the multiphoton ionization experiment.pFrom ref. 31. Obtained by the two-color resonance photoionization measurement.…”

“…Shortly thereafter, other dicyclopentadienyl metal complexes such as cobaltocene (Cp 2 Co) and nickelocene (Cp 2 Ni) were synthesized and the discovery of Cp 2 Fe, Cp 2 Co and Cp 2 Ni is a milestone in organometallic chemistry. This has also drawn extensive follow-up experimental and theoretical studies 3–32 dealing with the reactivity, thermochemical properties and electrochemical properties of Cp 2 Fe, Cp 2 Co and Cp 2 Ni. The standard reduction potential is a direct measure of the thermodynamic feasibility of an oxidation–reduction half-reaction; it is regarded as the energy needed when a chemical species accepts an electron generally in the solution phase, and it is conceptually same as the gas phase electron affinity.…”
