摘要

Crystals of a new silicate KNa2TmSi_8O_(19) ? 4H_2O, space group P12/m1 (the chemical formula was determined in the course of structure solution), are obtained under hydrothermal conditions. KNa_2TmSi_8O_(19) ? 4H_2O is the first synthetic representative of the family, which contains the following well- known and recently discovered minerals: rhodezite, delhayelite (fivegite, hydrodelhayelite), mountainite, shlykovite (cryptofillite), and guenterblassite (umbrianite, hilleshaymite). A crystal chemical analysis within the extended OD theory revealed the similarity of the structures of the family, including the new simplest representative and the factors responsible for structural diversity, namely, different symmetry of sheets of octahedra connected with layers of tetrahedra, which are distinguished in all the structures, and different patterns of symmetry relation between the sheets. Hypothetic structures with a higher degree of disordering are deduced. Crystals with these structures can be found in nature or obtained synthetically.
