“…Since the atoms of indium, tin, and palladium have very similar values of atomic X-ray scattering factors [ 24 ], superstructure reflections intensity was essentially zero. For this reason, to determine the crystal structure of In-type tetragonal phases in samples 1–6, 8–11, and 13, we used an approach similar to that described in [ 20 , 21 ]. This approach is based on the results of [ 8 , 9 , 25 ], who found that in the In–Pd binary system, the low-temperature modification of InPd 3 (Al 3 Ti-structure) and the high-temperature modification of the InPd 3 compound (Al 3 Zr-structure) differ in the ratio of c/a parameters for their face-centered pseudocubic subcells.…”
