A Step beyond the Feltham–Enemark Notation: Spectroscopic and Correlated ab Initio Computational Support for an Antiferromagnetically Coupled M (II)– (NO) − Description of Tp*M (NO) (M = Co

With regard to the utilisation of valence-to-core X-ray emission spectroscopy (V2C XES) for quantifying small-molecule activation such as N 2 in iron-dinitrogen complexes, we developed V2C XES as a spectroscopic ruler for the quantitative determination of NO oxidation state in Fe-NO complexes, which was circumvented by invention of Enemark-Feltham notation [5].

Heme and non-heme iron-nitrosyl complexes are important intermediates in biology. 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.

Fe III /NO − Fe II /NO • Fe I /NO + : {FeNO} 7. (Enemark- Feltham notation, Coord. Chem. Rev. 1974, 13, 339).

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.

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.

This is due to the fact that NO is a non-innocent ligand that can become oxidized (to NO +) … 2018-07-16 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. 5-ish Slides about Enemark-Feltham Notation.

In the absence of NO, the Fe 2+ ions are not chelated by neocuproine because of rapid formation of water insoluble iron hydroxide complexes [ 25 ].
