Abstract

The coordination of 18-crown-6 to Ce[N(SiMe₃)Ph^F]₃ (Ph^F = pentafluorophenyl) results in a κ²-18-crown-6 complex, a unique coordination mode for an f-block cation. The κ²-18-crown-6 complex showed exchange with free 18-crown-6 in solution and facile rearrangement of the crown ligand into a κ⁶-18-crown-6 cerium complex.
