The magnetic properties (spin-only) and color of 3d-series coordination compounds depend on the oxidation state of the central metal ion, the nature of the ligands surrounding the metal ion, and the electronic configuration of the metal ion.

For 3d transition metal ions, the magnetic moment is determined by the number of unpaired electrons in the d-orbitals. The spin-only magnetic moment can be calculated using the formula: μspin = √n(n+2) BM, where n is the number of unpaired electrons and BM is the Bohr magneton.

In general, 3d-transition metal ions with a maximum of 5 unpaired electrons are paramagnetic, meaning they are attracted to an external magnetic field. Coordination compounds of these metal ions will show a magnetic moment due to the presence of unpaired electrons.

As for color, coordination compounds of 3d-transition metal ions can display a wide range of colors depending on the electronic transitions that occur in the metal-ligand complexes. The color arises from the absorption of light by the coordination compound, which causes electronic transitions from the ground state to excited states.

The nature of the ligands surrounding the metal ion also plays a significant role in determining the color of the coordination compound. Strong-field ligands such as CN-, CO, and NO+ are known as “spectrochemical series” ligands and typically give rise to low-spin complexes that absorb light at higher energies, resulting in compounds that appear colored in the visible region of the spectrum. On the other hand, weak-field ligands such as H2O, NH3, and OH- are typically “spin-allowed” ligands and give rise to high-spin complexes that absorb light at lower energies, resulting in compounds that appear less colored.

In summary, the magnetic properties (spin-only) and color of 3d-series coordination compounds depend on the oxidation state of the central metal ion, the nature of the ligands surrounding the metal ion, and the electronic configuration of the metal ion.
