Inorganic Chemistry Lesson of the Day: 5-Coordinated Complexes

There are 2 common geometries for 5-coordinated complexes:

  • Square pyramid: The metal centre is coordinated to 4 ligands in a plane and a 5th ligand above the plane.
  • Trigonal bipyramid: The metal centre is coordinated to 3 ligands in a plane and 2 lignads above and below the plane.
