“…The collision-energy dependencies measured for the reactions of Ne þ with C 60 are shown in Figure 2 and indicate an onset for dissociative electron transfer and insertion at collision energies of approximately 20 and 30 eV, respectively (Wan, Christian, & Anderson, 1992;. Other atomic ions investigated include O þ (Christian, Wan, & Anderson, 1992a), C þ (Christian, Wan, & Anderson, 1992b), Wan et al, 1993), B þ , F þ , Fe þ (Basir et al, 1994), and Mn þ (Basir and Anderson, 1995).…”

The author provides a brief overview, and shares the extraordinary excitement, of the years of unprecedented discoveries in ion chemistry that followed the first production of fullerene powder in 1990. Various charge states of the buckminsterfullerene C60n+ cation became available by conventional electron-impact ionization of the vapor of this powder and so for mass-spectrometric measurements of ion reactivity. The emphasis here will be on fullerene-ion research performed in the author's own laboratory at York University using electron ionization flow-tube mass spectrometry techniques.

Evolution of structure and properties of neutral and negatively charged transition metal–coronene complexes: a comprehensive analysis

et al. 2013

The geometries, electronic and magnetic properties of neutral and negatively charged Mn(coronene)m (M = V and Ti; n, m = 1, 2) complexes were investigated using density functional theory. The results show that one V or Ti atom prefers to occupy the η(6)-site in M(coronene)(0/-) complexes and to be sandwiched between the two coronene molecules in M(coronene)2(0/-) complexes. Two metal atoms always form a dimer and interact with one coronene molecule. The calculated vertical electron affinities and transition energies are in good agreement with experimental values. This lends considerable credence to the obtained ground state structure and validates the chosen computational method. The bond formation between metal atom and coronene is accounted for by 3d/4s-π bonds, as revealed by the molecular orbitals plots. The reason why the peripheral ring site binds metal most effectively has been analyzed systematically by π electron content, aromaticity and average charge on carbon atoms. The electron localization function shows that there is perfect electron delocalization in these complexes. Furthermore, the magnetic moments of V(coronene)(0/-) and Ti(coronene)(-) are found to be substantially enhanced over the corresponding free metal atom; the magnetic moment of the neutral Ti(coronene) remains unchanged; while the larger size clusters experience a reduction.

Photoelectron spectroscopic study of the anionic transition metalorganic complexes [Fe1,2(COT)]− and [Co(COT)]−

The gas-phase, iron and cobalt cyclooctatetraene cluster anions, [Fe(1,2)(COT)](-) and [Co(COT)](-), were generated using a laser vaporization source and studied using mass spectrometry and anion photoelectron spectroscopy. Density functional theory was employed to compute the structures and spin multiplicities of these cluster anions as well as those of their corresponding neutrals. Both experimental and theoretically predicted electron affinities and photodetachment transition energies are in good agreement, authenticating the structures and spin multiplicities predicted by theory. The implied spin magnetic moments of these systems suggest that [Fe(COT)], [Fe(2)(COT)], and [Co(COT)] retain the magnetic moments of the Fe atom, the Fe(2) dimer, and the Co atom, respectively. Thus, the interaction of these transition metal, atomic and dimeric moieties with a COT molecule does not quench their magnetic moments, leading to the possibility that these combinations may be useful in forming novel magnetic materials.
