What is the strictly correct IUPAC name for the complex compound according to modern nomenclature ru — Coordination Compounds Chemistry Question

💡 Solution & Explanation

The complex consists of a complex cation $[Co(NH_3)_4(H_2O)Br]^{2+}$ and nitrate counter ions. 1. Cation is named first. 2. Ligands are ordered alphabetically: ammine ($NH_3$), aqua ($H_2O$), and bromido ($Br^-$). Note: modern IUPAC rules replace 'bromo' with 'bromido'. 3. Prefixes indicate number: tetraammine, aqua, bromido. 4. Metal is cobalt (not cobaltate, because it's a cation). Oxidation state: $x + 4(0) + 0 + (-1) = +2 \Rightarrow x = +3$. 5. Anion is nitrate (counter ions don't get numerical prefixes like 'di'). Thus, Tetraammineaquabromidocobalt(III) nitrate.
