Amido, imido and nitride complexes

Bradley and Lappert pioneered the use of anionic organic amides as supporting ligands in transition metal chemistry [66, 67]. However, early transition metal amides remained relatively young field until a renewal of interest encouraged the development of this field [68-80]. Several features make these anions attractive particularly as an alternative to other ligand systems. As described 

The mean length of the short edges is 2.84 A, whereas that of the long edges is 3.63 A [93].
