Ferrites are oxides of iron with the formula MFe 2 O 4, where M is a divalent ion such as nickel, zinc, cadmium, manganese, or magnesium. The ferric iron ion is trivalent, and the oxygen ion accepts two electrons. Actually M can also be divalent iron, forming magnetite (Fe 3 O 4). The crystal structure is called spinel, which is the mineral. Determining the effect of mixed-metal in metal-organic frameworks (MOFs) is vital to understand the crystal structure and its related properties.
