WebMetal carbonyls are the transition metal complexes of carbon monoxide, containing a metal–carbon bond. These metal–carbon bonded complexes are such important players of organometallic chemistry that it cannot afford to keep the metal carbonyls out of the team just because of the definition. WebMost 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 …
