摘要：

The topologic symmetry of a framework silicate is reduced to topochemical symmetry by an ordering inside the tetrahedra; each further reduction of symmetry may be due to one of the following three causes: 1 ordered distribution of extraframework cations, 2 squeezing of the framework, 3 repulsion of extraframework cations. © 1979 Springer-Verlag.
