Trigonal Planar Heteroleptic Lanthanide(III) Bis(silyl)amide Complexes Containing Aminoxyl Radicals and Anions.

ABSTRACT: Modulation of the crystal field (CF) in lanthanide (Ln) complexes can enhance optical and magnetic properties, and large CF splitting can be achieved with low coordination numbers in specific geometries. We previously reported that the homoleptic near-linear Sm²⁺ complex [Sm^II{N(SiⁱPr₃)₂}₂] (1-Sm) is oxidized by the 2,2,6,6-tetramethylpiperidinyl-1-oxy (TEMPO^•) radical to give the heteroleptic, approximately trigonal planar Sm³⁺ complex, [Sm^III{N(SiⁱPr₃)₂}₂(TEMPO^-)] (2-Sm). Here, we report the synthesis of homologous [Ln^III{N(SiⁱPr₃)₂}₂(TEMPO^-)] (2-Ln;
