Question

Illustrate:

Coordination isomerism in coordination compounds.

Answer 1

Coordination isomerism occurs in ionic coordination compounds where ligands are exchanged between a cationic and an anionic complex, resulting in different arrangements of the same ligands around their respective metal ions, such as the pair [Co(NH₃)₆][Cr(C₂O₄)₃] and [Cr(NH₃)₆][Co(C₂O₄)₃] where ammonia and oxalato ligands swap between the cobalt and chromium centers.
