Squaring the circle : The novel dienamido pincer ligand N(CHCHP t Bu 2 ) 2 − affords the isolation of the unusual square‐planar iridium(II) and iridium(III) amido complexes [IrCl{N(CHCHP t Bu 2 ) 2 }] n ( n =0 ( 1 ), +1 ( 2 )). In contrast, the corresponding iridium(I) complex of the redox series ( n =−1) is surprisingly unstable. The diamagnetism of 2 is attributed to strong N→Ir π donation.
