Abstract

Novel lanthanide organometallic clusters, Lnn(C60)m, consisting of lanthanide atoms (Ln; Ln = Eu and Ho) and C60 molecules were produced in gas phase by a two-laser vaporization method. The Lnn(C60)m clusters were produced predominantly at compositions of (n, m) = (n, n + 3) [n = 1-4]. These stoichiometries showed no chemisorption reactivity toward CCl4 and O2 reactants. The cluster having (1,4) composition is proposed to form a tetrahedral structure, in which a Ln atom is surrounded by four C60 molecules. In larger clusters with (n, n + 3) composition, each Ln atom is found in a local (1,4) group. Together with the results of sequential chemisorption of Cl atoms on cluster cations, photoelectron spectroscopy of cluster anions leads us to conclude that Ln1(C60)m clusters are charge-transfer complexes expressed as Ln1x+(C60)mx-, and that Eu and Ho atoms exist as Eu2+ and Ho3+ ions, respectively.
