Isolation of +2 rare earth metal ions with three anionic carbocyclic rings: bimetallic bis(cyclopentadienyl) reduced arene complexes of La(2+) and Ce(2+) are four electron reductants

A new option for stabilizing unusual Ln(2+) ions has been identified in the reaction of Cp′(3)Ln, 1-Ln (Ln = La, Ce; Cp′ = C(5)H(4)SiMe(3)), with potassium graphite (KC(8)) in benzene in the presence of 2.2.2-cryptand. This generates [K(2.2.2-cryptand)](2)[(Cp′(2)Ln)(2)(μ-η(6):η(6)-C(6)H(6))], 2-Ln,...
