Abstract
A two-laser vaporization method produced novel lanthanide organometallic culsters, Lnn(C60)m, consisting of lanthanide atoms (Ln; Ln = Eu and Ho) and C60 molecules in the gas phase. The Lnn(C60)m clusters were produced predominantly at compositions of (n,m) = (n, n + 3) [n = 1-4]. These stoichiometries revealed no chemisorption reactivity toward CCl4 and O2 reactants. The cluster having (1,4) composition was proposed to form a tetrahedral structure, in which a Ln atom was surrounded by four C60 molecules. In larger clusters with (n, n + 3) composition, each Ln atom was in a local (1,4) group. Ln1(C60)m clusters were charge-transfer complexes expressed as Ln1x+(C60)mx+, and that Eu and Ho atoms existed as Eu2+ and Ho3+ ions, respectively.
