Perovskite is obviously the mineral CaTiO3, however it is also a class of compounds with the genaral formula ABX3 where x is usually oxygen and A and B are cations that vary largely in size. One of the most amazing things about perovskites is that they can consist of the same metal in multiple oxidation states for example manganese in LaMnO3. My question is this. Can you have a perovskite that contains only 1 metal say manganese but have its A and B sites filled with different oxifdation states?
eg Mn(II)Mn(IV)O3 or does it have to be unique metals?
