What material has iron in tetrahedral and what in octahedral with 2+ or 3+ oxidation states?
dont really know much about this but from a bit of browsing i found some stuff that may be usefull Magnetite is octahedral and is a mixture of 2+ and 3+ iron Iron (II) oxide adopts the cubic, rock salt structure, where iron atoms are octahedrally coordinated by oxygen atoms and the oxygen atoms octahedrally coordinated by iron atoms Iron(III) chloride also octahedral hope this helps
