Solution and Explanation
IUPAC Name of the Complex:
The IUPAC name of the complex [Co(H2O)(CN)(en)]2+ is diaquacyanido-bis(ethylenediamine)cobalt(III) ion.
Explanation:
- "Aqua" represents the two water molecules (H2O) as ligands.
- "Cyano" refers to the cyanide (CN) ligand.
- "Ethylenediamine" refers to the bidentate ligand (en), which binds through two coordination sites.
- Cobalt is in the +3 oxidation state, which is indicated by the roman numeral (III) after "cobalt."
