[4] Even trinitrosyl complexes are uncommon, whereas polycarbonyl complexes are routine. Most complexes containing the NO ligand can be viewed as derivatives of the nitrosyl cation, NO +.The nitrosyl cation is isoelectronic with carbon monoxide, thus the bonding between a nitrosyl ligand and a metal follows the same principles as the bonding in carbonyl complexes.The nitrosyl cation serves as a two-electron donor to the metal and accepts electrons from the metal via back-bonding.

This Thesis investigates the effect of π-bonding interactions on the electronic configuration and reactivity of Cr and Mo organometallic complexes that contain Cp' (C₅R₅ ; R = H (Cp), CH₃ (Cp*)) and NO ligands. The nitrosyl cation serves as a two-electron donor to the metal and accepts electrons from the metal via back-bonding. The nitrosyl cation is isoelectronic with carbon monoxide, thus the bonding between a nitrosyl ligand and a metal follows the same principles as the bonding in carbonyl complexes. Other indirect methods are indirect with the NO group deriving from some other species, often accompanied by oxidation and reduction reactions. Three iron atoms are bonded to two nitrosyl groups. An important reaction is the acid/base equilibrium: This equilibrium serves to confirm that the linear nitrosyl ligand is, formally, NO+, with nitrogen in the oxidation state +3. Pages 257-260. Roussin's black salt has a more complex cluster structure. Nitrosyl complexes are typically prepared by treating reduced metal complexes with nitric oxide. Metal-catalyzed reactions of NO are not often useful in organic chemistry. The structure of the anion can be viewed as consisting of two tetrahedra sharing an edge. Pages 225-256. Enemark R.D.
