説明

The cation-cation repulsions across the shared edges of polyhedra in garnet structure are the most prominent between tetrahedral and dodecahedral cations, and this effect has a significant influence on cation distribution and symmetry change in garnets. Moreover, the shared edge of SiO₆ octahedron in stishovite (SiO₂), with rutile structure, is more compressible than the unshared edges; this can be explained by Si-Si repulsion across the shared edge. Thus, the cation-cation repulsions across the shared edges of polyhedra cannot be ignored as a significant factor governing the stability of compounds with edge-sharing structures.
