Nomenclature Of Coordination Compounds

Step 1: The given compound is a platinum–ethylene complex.
Step 2: It is known as Zeise’s salt.

Step 1: EDTA has six donor atoms.
Step 2: Hence it is hexadentate.

Zeise's salt is a common name of . Its IUPAC name is potassium trichloro(ethylene)platinate(II).

Step 1: Coordination number of Co(III) is 6.
Step 2: Ligands: 3NH₃ + 2H₂O + 1Cl⁻.
Step 3: Charge balance gives two chloride ions outside the coordination sphere.

The complex chlorodiaquatriammine cobalt (III) chloride can have the structure

K[PtCl₃(C₂H₄)] is known as Zeise’s salt.

Step 1: Name analysis: • chloro ⟹ one Cl⁻ inside coordination sphere • diaammine ⟹ two NH₃ ligands • cobalt(III) ⟹ oxidation state +3
Step 2: Remaining ligands are water molecules to complete coordination number 6.
Step 3: Charge balance gives two chloride ions outside the coordination sphere.
