A homoleptic cerium(III) amide complex, Ce(NPhF 2)3 (1-Ce) (PhF = pentafluorophenyl), in an unusual pseudo-trigonal planar geometry featuring six C-F → Ce interactions was prepared. The C-F → Ln interactions in solution were evident by comparison of the 19F NMR shifts for the paramagnetic 1-Ce with those of the 4f0 lanthanum(III) analogue. Coordination of weak σ- and π-donors, including ethers and neutral arene molecules, was achieved by the reversible displacement of the weak C-F → Ce interactions. Computational studies on Ce(NPhF2)3 and Ce(NPhF2)3(η6-C 6H3Me3) provide information on the F → Ce interactions and Ce-η6-arene bonding.
