While there are numerous examples of low-spin heme iron-nitrosyl complexes in different oxidation states, much less is known about high-spin (hs) non-heme iron-nitrosyls in oxidation states other than the formally ferrous NO adducts ({FeNO} 7 in the Enemark-Feltham notation). The adoption of linear vs bent bonding can be analyzed with the Enemark-Feltham notation. In their framework, the factor that determines the bent vs linear NO ligands is the sum of electrons of pi-symmetry. Complexes with "pi-electrons" in excess of 6 tend to have bent NO ligands. The two newly designed nitrosyl complexes with Enemark–Feltham notation {RuNO} 6 and {RuNO} 7 configurations have been isolated as the perchlorate salts in the molecular framework [Ru II (dmdptz)(phen)(NO)] n + (dmdptz: N,N-dimethyl-4,6-di(pyridin-2-yl)-1,3,5-triazin-2-amine and phen: 1,10-phenanthroline) [Ru II (dmdptz)(phen)(NO +)](ClO 4) 3 [4](ClO 4) 3 and [Ru II (dmdptz)(phen)(NO)](ClO 4 Abstract: High-spin non-heme ferrous nitroxyl (NO-) complexes ({FeNO}8 in the Enemark-Feltham notation) have been proposed as important intermediates in bacterial nitric oxide reductases. Despite their significance, model compounds for these species have remained elusive and prior to the studies described here, little was known about their The Enemark-Feltham notation is used to describe the number of .

A Step beyond the Feltham -Enemark Notation: Spectroscopic and Correlated ab Initio Computational Support for an Antiferromagnetically Coupled M(II) -(NO)? described in terms of the Enemark-Feltham notation[40] as {MNO}10. The assignment of oxidation states in nitrosyl complexes is not trivial due the covalent character of the metal nitrosyl bond as published by Klüfers et al.[41] With CASSCF calculations and the effective-oxidation-state method[42] they assigned the π-bonding M-NO electrons. Current knowledge evokes the formation of reduced iron-nitrosyls, commonly referred to as {FeNO}8 complexes from the Enemark-Feltham notation, in several hemecontaining proteins and enzymes as a possible endogenous source of nitroxyl.

In their framework, the factor that determines the bent vs linear NO ligands is the sum of electrons of n-symmetry. Since different binding modes can lead to different formal oxidation states, Enemark and Feltham proposed a simple notation, {MNO} n (n = metal d + NO-π* electrons) to describe metal NO complexes unambiguously and ease their theoretical comparison. 5-ish Slides about Enemark-Feltham Notation.

Enemark-Feltham notation The Enemark-Feltham notation is used to describe the number of d-type electrons present in a complex. It is deliberately ambiguous, because the true oxidation state of a metal coordinated by non-innocent ligands is often unclear.

NO ligands are redoxnon-innocent, which means NO has multiple accessible redox states under common conditions.
