文摘

A novel type of reaction of lanthanide hydrido complexes with C₆₀ is described. The hydride anion of complex [{(Me₃Si)₂NC(NCy)₂}₂Lu(μ-H)]₂ reduces C₆₀ (1:2 molar ratio, toluene, 20 °C) to the radical anion, and the reaction results in the formation of ionic complex [{(Me₃Si)₂NC(NCy)₂}₂Lu(Et₂O)⁺](C₆₀^−•). At low temperature (below 120 K) reversible dimerization of radical anions C₆₀^−• occurs and affords the complex [{(Me₃Si)₂NC(NCy)₂}₂Lu(Et₂O)⁺]₂[(C₆₀⁻)₂]·2(C₇H₈)·(Et₂O) with the diamagnetic σ-bonded (C₆₀⁻)₂ dianion.
