Question

Write the IUPAC names of the following complexes:

[Cu {({NH}_{3})}_{4}] {SO}_{4}

Accepted Answer

The coordination compounds are named in the following way,

To name a coordination compound, no matter whether the complex ion is the cation or the anion, always name the cation before the anion.

In naming the complex ion: Name the ligands first, in alphabetical order, then the metal atom or ion. Note: The metal atom or ion is written before the ligands in the chemical formula.

Greek prefixes are used to designate the number of each type of ligand in the complex ion, e.g. di-, tri- and tetra-. If the ligand already contains a Greek prefix (e.g. ethylenediamine) or if it is polydentate ligands (ie., can attach at more than one binding site) the prefixes bis-, tris-, tetrakis-, pentakis-, are used instead.

After naming the ligands, name the central metal. If the complex ion is a cation, the metal is named same as the element.

Following the name of the metal, the oxidation state of the metal in the complex is given as a Roman numeral in parentheses.

Thus, the IUPAC name of the given complex, $[Cu {({NH}_{3})}_{4}] {SO}_{4}$ will be tetraamminecopper $(II)$ sulphate.
