Title: Lanthanide(III) di- and tetra-nuclear complexes supported by a chelating tripodal tris(amidate) ligand

Syntheses, structural, and spectroscopic characterization of multinuclear tris(amidate) lanthanide complexes is described. Addition of K 3[N(o-PhNC(O) tBu) 3] to LnX 3 (LnX 3 = LaBr 3, CeI 3, and NdCl 3) 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(SiMe 3) 2] 3 (Ln = Ce, Nd) with N(o-PhNCH(O) tBu) 3. As a result, 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.
