Guida verificata passo dopo passo1
Identify the ligands in the complex ion. In [Fe(CN)5NO]3–, the ligands are CN (cyanide) and NO (nitrosyl).
Determine the number of each type of ligand. There are five cyanide ligands and one nitrosyl ligand.
Name the ligands in alphabetical order. 'Cyano' comes before 'nitrosyl', so the ligands are named as 'pentacyano' and 'nitrosyl'.
Identify the central metal and its oxidation state. The central metal is iron (Fe). The overall charge of the complex is -3. Calculate the oxidation state of iron by considering the charges of the ligands: CN has a charge of -1 and NO is neutral.
Combine the ligand names, central metal, and oxidation state to form the name of the complex ion. The correct name is 'pentacyanonitrosylferrate(II)' for the complex ion [Fe(CN)5NO]3–.
