Figure 4
A Kagomé network consisting of triangles and hexagons. The views show (a) a regular network, as in Ba[Co3(VO4)2(OH)2] (black spheres represent Cu1 atoms and grey spheres represent O2 atoms), and (b) a distorted newwork, as in Pb[Cu3(AsO4)2(OH)2] (differently lined black spheres represent Cu1, Cu2 and Cu3 atoms, and grey spheres represent O1, O2 and O3 atoms). |
