Figure 3
A view of the Rb2(VO)2[Si8O19] structure in a perspective bc projection. Displacement ellipsoids are drawn at the 50% probability level and the unit cell is indicated by black lines. VO5 square pyramids are dark and SiO4 tetra­hedra are light. Note the zigzag pattern of channels occupied by Rb2 and the empty channels with two linking Si4O4 tetra­hedra per six-tetra­hedron ring.
