RHENIUM OXIDE (ReO3)
Rhenium oxide forms a more complex and
In the unit cell below, rhenium (Re) is
red and oxygen (O) is yellow.

The unit cells stack to form the crystal thus:

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.
Particularly interesting are:
(1) In some orientations square boxes of oxygen atoms appear, filled
with columns of rhenium. These are easier to see in the open
(2) In other orientations similar, but empty square channels exist.
These can allow other atoms, molecules, or ions to migrate within the crystal.
This provides a mechanism for the crystal to act as a catalyst or for the
crystal to change its composition without breaking down the lattice itself.
The ReO3 sublattices are not identical, as you can see
