Figure 2
The pseudo-layer packing of Cu3B2O6. Each layer consists of isolated CuO4 squares, Cu2O6 dimers of edge-sharing CuO4 squares, infinite CuO2 chains, and BO3 and corner-sharing B2O5 units. B—O bonds are shown with thicker lines. Displacement ellipsoids are plotted at the 70% probability level. |
