This paper reports on the discovering of two new layered-silicate mineral species, kalyuzhnyite-(Ce) NaKCaSrCeTi(Si8O21)OF(H2O)3 and letnikovite-(Ce) (Na )Ca2Ce2[Si7O17(OH)]F4(H2O)4. They are found in the Darai-Pioz alkaline massif in the Tien-Shan mountains of Tajikistan. The structure of these minerals includes two new types of layers formed by SiO4-tetrahedra, the kalyuzhnyite double [Si8O21]10–-sheet and letnikovite [Si7O17(OH)]7--sheet. The specific features of these minerals are described and compared with related layered minerals. Both of minerals with large channels potentially can be used as a model for synthesis of microporous materials of industrial interest.
