Abstract

In gas phase, Na-atom adducts were produced for organometallic lanthanide complexes of Lnn(C8H8)n+1 [Ln = europium (Eu) and holmium (Ho); C8H8 = 1,3,5,7-cyclooctatetraene (COT)] by a combination of two-laser vaporization and a molecular beam method. The number of attached Na atoms can be reasonably explained by charge distributions of the complex, where Eu and Ho atoms exist as Eu2+ and Ho3+ , respectively, and C8H8 molecules as COT2-, accepting two excess electrons. The behavior of the Na adducts chemically demonstrates that the organometallic lanthanide complex is formed through ionic bonding, implying that it is possible to be isolated as its Na salt.
