The literature reports refined structural data for SnS2 for pressures up to 20 GPa. These data were used as input data in a crystallographic software to calculate the shell structures around the Sn, Se, and S atoms placed at the origin. The shell structures were used to simulate the partial and total structure factors Sij(K) and S(K), and by Fourier transformation the partial and total pairs distribution functions Gij(R) and G(R) were obtained.
