Fig. 12.

The cubic (Im3) structure of Li0.2 ReO3 projected on the (001) plane. The empty triangles represent Re atoms at z = 1/4, 3/4; empty squares: Li at z = 1/2; empty circles: Li at 0, 1; full triangles: O at z≈1/4, 3/4; full squares: O at z≈1/2; full circles: o at z≈0, 1. In this structure the ReO6 octahedra are tilted of the same angle, and in the same sense, along all three crystallographic axes.
