The IUPAC name of the complex - [Ag(H $_{2}$ O) $_{2}$ ][Ag(CN) $_{2}$ ] is:

Solution

The compound has a cationic complex [Ag(H $_{2}$ O) $_{2}$ ] $^{+}$ and an anionic complex [Ag(CN) $_{2}$ ] $^{-}$ .

In each, silver carries an oxidation state of +1 since H $_{2}$ O is neutral and CN $^{-}$ is monoanionic, and the total charge balances.

Naming convention: cation first, then anion (with the -ate suffix for the anionic complex). Ligands are listed alphabetically; aqua before cyanido.

This yields: diaquasilver(I) dicyanidoargentate(I).
