World's record : The first isolation and structural characterization of a homoleptic isocyanidemetalate dianion has been achieved with [Fe(CNXyl) 4 ] 2− (Xyl=2,6‐dimethylphenyl; see structure, Fe red, N blue, C gray). Spectral and structural data indicate that metal‐to‐isocyanide back‐bonding in this electron‐rich species is the largest ever observed in a homoleptic isocyanide complex containing only terminally bound ligands.
