The name of the ion is cis-tetraamminedicyanocobalt(III).
Explanation:
The ligands are named "ammine" and "cyano".
The two cyano groups are at 90° to each other, so they are cis.
If they had been at 180° from each other the ion would have been *trans.
The cyanide ions originally had a charge of -1, and the complex ion has a charge of +1, so the oxidation number of the cobalt atom must be +3.
