What to Focus On

  • Primary valence is ionisable; secondary valence is non-ionisable.
  • Secondary valence equals coordination number.
  • Werner propounded the theory of coordination compounds in 1898.

  • A coordination entity contains a central metal atom or ion and ligands.
  • Unidentate, didentate, polydentate, chelate, and ambidentate ligands are distinct terms.
  • Coordination number counts only donor atoms linked by sigma bonds.

  • Write the central atom first in formulas.
  • Arrange ligands alphabetically in formulas.
  • Name the cation first.

Common Mistakes to Avoid

The coordination number is the total number of ligands attached to the metal.

Any ligand that has two donor atoms is always chelating both at the same time.

Secondary valence is the ionisable valence and primary valence is the fixed coordination number.

Memory Tips

Werner's main idea: primary valence and secondary valence

CoCl3.6NH3, CoCl3.5NH3, CoCl3.4NH3 colour and AgCl tests

Secondary valence equals coordination number

Coordination entity, central atom, ligands, counter ions
