Why would a tetrahedral complex of a transition metal have a vibrant colour
Accepted Answer
A tetrahedral complex of a transition metal exhibits vibrant color due to the d-d electronic transitions. Transition metals possess partially filled d orbitals. When light falls on the complex, electrons in lower energy d orbitals absorb energy and get excited to higher energy d orbitals. The absorbed wavelengths correspond to specific colors, and the complementary color is reflected, resulting in the observed vibrant color.
