IUPAC name of [Fe(O2)(CN)4Cl]4- is : — Coordination Compounds Chemistry Question

💡 Solution & Explanation

Step 1: Note that the printed formula [Fe(O2)(CN)4]^4- contains a typographical error in the book and represents [Fe(Cl)(O2)(CN)4]^4-. Step 2: In this complex, the ligands are chloro (Cl^-), superoxo (O2^-), and tetracyano (4 CN^-). This gives an oxidation state for iron of: x - 1 - 1 - 4 = -4 => x = +2, making it ferrate(II). Step 3: Ordering alphabetically gives 'chlorotetracyanosuperoxoferrate(II) ion', which corresponds to option (c).
