In the context of superspatial symmetry, the crystal structures of the Cu₇SiS₅I and Ag₇SiS₅I superionic conductors have been analyzed. To calculate the phonon spectra, the model of FCC superlattice (8а, 8а, 0; 8а, 0, 8а; 0, 8а, 8а) in the metric of protocrystal (а, а, 0; а, 0, а; 0, а, а) has been d...
