Metal centers, particularly Fe, appear as suitable sites of HNO activity, both for generation and targeting.

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.

bonding can be analysed with the Enemark-Feltham notation. In their framework, the factor that determines the bent vs linear NO ligands is the sum of electrons of n-symmetry.

It is deliberately ambiguous, because the true oxidation state of a metal coordinated by non-innocent ligands is often unclear.

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 + Monomeric DNICs can exist in the {Fe(NO) 2} 9 or {Fe(NO) 2} 10 oxidation state (in the Enemark -Feltham notation). However, experimental studies of analogous DNICs in both oxidation states are rare, which prevents a thorough understanding of the di ff erences in the electronic structures of these species.
