6-coordinate octahedral and
4-coordinate tetrahedral
complexes known
Co [Ar] 3d7 4s2
Co2+ [Ar] 3d5 5unshared pairs
Color in transition metal complexes is due to an electron being excited from one d-orbital to a higher-energy d-orbital. In the case of octahedral complexes, an electron is moved from a t2g orbital to an eg orbital. The energy difference for the first transition series generally falls in the visible region. Absorption of one color in the visible spectrum results in the ion having the complementary color. The amount of d-orbital splitting depends on the ligands. thus different ligands have different splitting energies, and different colors result.
