Now, iron has stable oxidation states 2 and 3. Nitrosyl, as a ligand, comes in many flavours, of which a negatively charged nitrosyl is one. I see no reason why the iron doesnt spontaneously oxidise to 3 and reduce the $ceNO$ to 1 to gain stability. But I dont know how to analyse this situation anyway.

1. Composition of Cast Irons As the carbon content increases, the melting point (as compared to steels) is lowered to between 1200 to 1140C, and thus, carbon acts as a graphitiser. But, more the graphite formed, lower are the mechanical properties. Silicon mainly controls the form of carbon present in the cast iron.

Write the element symbol. Write ionic charge based on the Roman Numeral in the name. For example, the Iron (II) ion would be Fe 2. Polyatomic ions are made up of two or more elements (they will be non-metals). Most often polyatomic ions will have a negative charge but there a few with positive charges.
A deep-blue precipitate results when either complex ion combines with iron in a different oxidation state from that present in the complex. So if a Fe(CN) 6 4-which has an Fe 2 in it where to combine with another iron with an Fe 3 a deep-blue precipitate forms. An iron of a different oxidation state would have to combine in order for the precipitate to occur.
