New monoanionic CNC pincer ligands, [N{SiMe 2 CH 2 ( R Im)} 2 ] – ( R = t Bu, i Pr, Ph) featuring three different N ‐heterocyclic carbenes and a disilylamido moiety is reported. Treatment of the lithium salt of [N{SiMe 2 CH 2 ( R Im)} 2 ] – with Cu I OTf afforded the corresponding copper complexes [N{SiMe 2 CH 2 ( R Im)} 2 ]Cu in 41–56 % yield. X‐ray crystal structures of [N{SiMe 2 CH 2 ( R Im)} 2 ]Cu show that they are monomeric and feature three‐coordinate, pseudo T‐shaped copper(I) sites. The X‐ray crystal structure of one of the precursor lithium complexes, [N{SiMe 2 CH 2 ( t BuIm)} 2 ]Li is also presented.
