Lanthanide triflates have been used to incorporate Nd(III) and Sm(III) ions into the 2.2.2-cryptand ligand (crypt) to explore their reductive chemistry. The Ln(OTf) 3 complexes (Ln = Nd, Sm; OTf = SO 3 CF 3 ) react with crypt in THF to form the THF-soluble complexes [Ln III (crypt)(OTf) 2 ][OTf] with two triflates bound to the metal encapsulated in the crypt. Reduction of these Ln(III)-in-crypt complexes using KC 8 in THF forms the neutral Ln(II)-in-crypt triflate complexes [Ln II (crypt)(OTf) 2 ]. DFT calculations on [Nd II (crypt)(OTf) 2 ], the first Nd(II) cryptand complex, assign a 4f 4 electron configuration to this ion.
