The name of complex ion, is:
Hexacyanoiron (III) ion
Hexacyanitoferrate (III) ion
Tricyanoferrate (III) ion
Hexacyanidoferrate (III) ion
As we learned in concept
Writing the name of Complex compound formula -
(i) Cation is named first
(ii) ligands are named in alphabetical order before name of central metal atom.
(iii) Prefixes, mono, di, tri are used to indicate the no of ligands
(iv) when name of ligand used a numerical prefix, then term bix, tris, tetrakis are used.
is named as dichlorobis (triphenylphosphine)nickel(II)
(v) Oxidation state is represented by roman numerical in parenthesis
(vi) If the complex ion is an anion, the name of metal ends with suffix -ate
eg: co in complex anion
is called cobaltate.
The name of is Hexacyanidaferrate ion
therefore solution is 4
