I think it is covalent
Iron would form ionic bonds with sulfur.
Fe 2+andSO4 2-form the ionic bond,Ferrous sulfate, FeSO4, also know as iron II sulfate.
FeCl is a metal (Fe) and a nonmetal (Cl), which means that it is a ionic bond.
with bromine (Br)
Fe 2+and2Cl -Make FeCl2An ionic compound.

According to theory it has ionic bonding because a metal bonds with a non-metal. However, because there is not a large difference in electronegativity a bond is formed that is not exactly ionic nor covalent but an intermediate (the difference needs to be higher than 1.8 for an ionic bond to form, Fe has 1.8, O has 3.4 -> 1.6 difference). What this actually means is that Fe does not completely give away its three electrons to become Fe+3 because Oxygen doesn't attract them strong enough, or because Fe attracts them strongly too. Instead, they share the electrons as in a covalent bond. The bond is definitely polar (to give you an idea, the electronegativity difference between hydrogen and oxygen in water is 1.2, H has 2.2 and oxygen again 3.4. This gives rise to Hydrogen bonding, which is due to the polarity of the water molecule.). To conclude, the bond is an intermediate between an ionic and a covalent bond, and it is definitely polar.
Iron is a metal and chlorine is a non-metal, so it would be classified as an ionic bond. However, the bond will actually possess some strong polar covalent character, because the electronegativity difference between Fe and Cl is approximately 1.2.
