Question

Why are transition metal complexes coloured?


Open in App
Solution

Transition metals:

  • The presence of d orbitals is a common feature of Transition components.
  • The d orbitals split and become non-degenerate due to the various symmetries of the d orbitals and the inductive actions of the ligands on the electrons (which have different energy levels).

Reason for the color of transition metals:

  • Transition metals, on the other hand, are unique in that the energy difference between non-degenerate d orbitals corresponds to the energy of visible light radiation.
  • When the electrons are present in an octahedral metal complex, they can absorb green light and move from the dyztothedz2 orbital, the compound will reflect all colors excluding green color.
  • As a result, it is easy to identify the complementary colour of green, which will be the colour of the compound, magneta, by utilising the colour wheel.
