Abstract

Syntheses, structural, and spectroscopic characterization of multinuclear tris(amidate) lanthanide complexes is described. Addition of K₃[N(o-PhNC(O)^tBu)₃] to LnX₃ (LnX₃ = LaBr₃, CeI₃, and NdCl₃) in N,N-dimethylformamide (DMF) results in the generation of dinuclear complexes, [Ln(N(o-PhNC(O)^tBu)₃)(DMF)]₂(μ-DMF) (Ln = La (1), Ce (2), Nd(3)), in good yields. Syntheses of tetranuclear complexes, [Ln(N(o-PhNC(O)^tBu)₃)]₄ (Ln = Ce (4), Nd(5)), resulted from protonolysis of Ln[N(SiMe₃)₂]₃ (Ln = Ce, Nd) with N(o-PhNCH(O)^tBu)₃. In the solid-state, complexes 1-5 exhibit coordination modes of the tripodal tris(amidate) ligand that are unique to the 4f elements and have not been previously observed in transition metal systems.
