Figure 2
The unit-cell of (I) in polyhedral representation viewed approximately down [110]. A single O atom at the average location of O6A and O6B in the asymmetric unit has been used to construct the As2 tetrahedron. Colour code: Zr1O6 octahedra blue, Zr2O6 octahedra green, As1O4 tetrahedra peach, As2O4 tetrahedra rose, Cs sky blue, Na yellow, O (polyhedral corners) red. |
