Rhenium oxide forms a more complex and interesting structure.
Click on the unit cell above to view it rotating. Expanded Rhenium Oxide Lattice Tight Rhenium Oxide lattice Horizontal Vertical Click on the images above to view the ReO 3 structure rotating. The oxygen ions at the corners of the expanded lattice have been made darker simply to help keep the structure in perspective. They are otherwise identical to all other oxygens in the lattice. In some orientations square boxes of oxygen atoms appear, filled with columns of rhenium.
