title: κ²-Coordination of 18-crown-6 to Ce(III) cations: solution dynamics and reactivity.
abstract: The coordination of 18-crown-6 to Ce[N(SiMe3)Ph(F)]3 (Ph(F) = pentafluorophenyl) results in a κ(2)-18-crown-6 complex, a unique coordination mode for an f-block cation. The κ(2)-18-crown-6 complex showed exchange with free 18-crown-6 in solution and facile rearrangement of the crown ligand into a κ(6)-18-crown-6 cerium complex.
