The thermally stable nickel(II) diamides [NiL 2 ] [L = − N(SiMe 3 )(8‐C 9 H 6 N) ( 1 ), − N(Si t BuMe 2 )(8‐C 9 H 6 N) ( 2 )] have been synthesized from the reaction of NiCl 2 with the appropriate lithium amide. X‐ray crystallography revealed that the amido ligands bind in a chelating manner, forming a distorted tetrahedral environment around the nickel center. Complexes 1 and 2 have magnetic moments of 3.05 and 2.74 μ B , respectively, which indicate a d 8 electronic configuration with two unpaired electrons.
