In the context of coordination compounds, a Type II compound typically involves transition metals in which the metal ion can exhibit variable oxidation states. In a Type II compound, the metal ion can have different oxidation states and may form complex ions with ligands.


Alkali and alkaline earth metals are generally not involved in the formation of Type II compounds because they typically exhibit fixed oxidation states and do not readily form complex ions. These metals, such as sodium (Na), potassium (K), and calcium (Ca), usually form Type I compounds where they maintain a constant oxidation state.
