Polyhedral representation of CaSn2O4(OH)2. (a) Perspective view: CaO8 tetragonal antiprisms and SnO6 octahedra; (b) alternate layers of tetragonal CaO8 antiprisms and double layers of SnO6 octahedra; (c) layer of CaO8 antiprisms with alternating empty and filled antiprisms; (d) top view of the double layer of SnO6 octahedra, the octahedra in the upper and lower layers are in different colours for clarity; (e) side view of the double layer of SnO6 octahedra. |
