Answer:

This is a mixed valence compound of #Fe(II)# and #Fe(III)#.

Explanation:

If we write #Fe_2O_3*FeO# the formulation is easier to consider. #Fe_3O_4# occurs naturally as the mineral magnetite. Iron oxide chemistry is a very broad church and many mixed oxides and oxidation states are available.
