Question
Based on IUPAC naming conventions, which of the following complex names correctly correspond to a compound that contains an anionic coordination sphere?
💡 Solution & Explanation
Anionic coordination spheres are indicated by the suffix '-ate' on the central metal's name. (A) Potassium amminepentachloridoplatinate(IV) has 'platinate', meaning the complex is an anion ($[Pt(NH_3)Cl_5]^-$). (B) Hexaamminecobalt(III) chloride has 'cobalt', meaning the complex is a cation. (C) Tetracyanidonickelate(II) ion has 'nickelate', meaning it is an anion ($[Ni(CN)_4]^{2-}$). (D) Dichloridobis(ethane-1,2-diamine)cobalt(III) ion has 'cobalt', meaning it is a cation.
