Isomerism of Complex Ions

Complex ions display several kinds of isomerism.

Cis/trans isomers

  • Cis/trans isomerism is a bit like E/Z isomerism.
    • When two groups are on the same side, they are cis.
    • When two groups are on opposite sides, they are trans.

Cis/trans isomers

  • An example is the complex [Ni(H2O)4)Cl2].
    • The chlorine and water groups can either be on the same or different sides, as shown.
  • Cis/trans isomerism is also very common in square planar structures.

Optical isomerism

  • Octahedral molecules with three bidentate ligands exist as pairs of enantiomers.
  • This is illustrated for a nickel complex above. image: Ni(en)3 isomers.
