A couple of questions about the compound rust...?

Question

Okay so I know Rust's chemical name is Iron Oxide, and I think its chemical formula is something like Fe2O3. (could someone correct me if I'm wrong?)

I also need to know about its bonding structure (can you show me a diagram if possible?), the atomic structure and the uses for rust, if there are any?

Please help! Thanks!

Answer 1

Rust is Fe2O3.  A good depiction of the structure is given at the reference.
