Ambidentate ligands such as thiocyanate (SCN-), cyanate (OCN-) and azide (N3 -) have played important roles in the development of bonding models relating to factors that control linkage isomerism in transition metal complexes. However, examples of DNICs, for which oxidn. states of iron are ambiguous, contg. these ambidentate ligands are rare. Two redox levels are prevalent for DNICs, represented in the Enemark-Feltham (E-F) notation as {Fe(NO)2}9 and {Fe(NO)2}10 for oxidized and reduced levels resp., eac...
