From: Exploration of tetrahedral structures in silicate cathodes using a motif-network scheme
Examples of the structures with 2D M-Si-O framework.
Space group of each structure is (a) Pnma (#62), (b) Pmn21 (#31), (c) P21/n (#14), (d) Pmn21 (#31), (e) P21/m (#11), (f) Pn (#7). Two mutually perpendicular views are plotted for each structure. The black boxes indicate the unit cells of each structure. M- and Si- centered tetrahedra are displayed in the brown and blue colors respectively. A-O bonds are connected and displayed in green color.
