The ionic mobility and conductivity in the crystalline phase of Cs0.4Rb0.6Sb2F7 (I) is studied using 19F NMR, DSC, and impedance spectroscopy methods. The analysis of the 19F NMR spectra makes it possible to follow the character of ion motions in the fluoride sublattice in the temperature range of 150−470 K, and to determine the types and temperature ranges of these motions. It is found that diffusion of fluorine ions becomes the dominant type of ion motions in the modification formed as a result of the reversible phase transition ( T = 415 K, the DSC data) in compound I. According to the preliminary results of electrophysical studies, the ionic conductivity in this compound is ~10-3 S/cm at temperatures above 450 K.

The crystallographic data are as follows: а = 7.733(2) Å, b = 11.368(2) Å, c = 11.685(2) Å, α = 116.23°, β = 104.26°, γ = 94.96°; V = 870.3(3) Å3, space group P(-1), Z = 2, dcalc = 2.647 g/cm3, R = 0.0245. The packing of the complex is comprised of double stacks of cations and chains of anions linked into two-dimensional layers due to weak intermolecular interactions (non-classical hydrogen bonds C-H…O, C-H…Au, C-H…p and the Au…Au contacts). The thermal decomposition of the obtained compound in the hydrogen atmosphere is studied. According to the powder X-ray diffraction data, the product of the reduction of the synthesized salt is a mixture of nanocrystalline phases of Re and Au with the coherent-scattering regions of 17 nm and 13 nm respectively.

The molecule of S,S'-dimethyl-N-nitroimidodithiocarbonate has a planar geometry (with the exception of hydrogen atoms of methyl groups), stabilized by the shortened S…O contact. The bond lengths in the >С=N-NO2 nitrimine moiety, in contrast to nitroguanidine derivatives, make it possible to consider the molecular structure of the compound within the traditional valence formula. The crystal structural feature of the compound is a low energy of its crystal lattice.
