Figure 1
Structure of vanadinite (space group P63/m) projected down [001]. The structure contains VO4 tetrahedra (grey) and Pb1O9 polyhedra (orange). The Pb2O6Cl2 polyhedra are not shown. The Cl atoms (blue) are in the 63 channels and form Cl—Pb26 octahedra (blue). The Pb2 sites are shown in red and O sites in black. The hexagonal unit-cell edges are outlined. |
