The IUPAC name for K2[Cr(CN)2O2(O2)NH3] is : — Coordination Compounds Chemistry Question

💡 Solution & Explanation

Step 1: Identify the ligands: one ammine (NH3), two cyano (CN^-), two oxo (O^2-), and one peroxo (O2^2-). Step 2: Calculate the oxidation state of Cr: 2*(+1) + x + 2*(-1) + 2*(-2) + 1*(-2) + 0 = 0 => x = +6. Step 3: Arranging the ligands alphabetically gives 'amminedicyanodioxoperoxo', with chromate(VI) as the anionic metal center. This matches option (d).
