Answer is: name of the complex ion [Cu (CN) ₆]⁴⁻ is hexacyanocuprate (II).

First give name of the ligands (in this example ligand is cyano anion CN ⁻), in alphabetical order, then the metal atom or ion (in this complex compound metal ion is copper Cu ²⁺). Prefix for six ligands is hexa-. This is anionic complex, so name of the copper is cuprate and (II) stands for oxidation number of copper.
