A new ternary compound was found at 62.5 at.% Zr during the investigation of the phase equilibria in the system Zr–Al–Sn at 600 °C. Its crystal structure was refined by the Rietveld method using X-ray powder diffraction pattern of a single-phase alloy of nominal composition Zr62.5Al5Sn32.5 collected at room temperature on a powder diffractometer STOE Stadi P (Cu Kα1-radiation, angular range 6º ≤ 2θ ≤ 110º, step 0.015º). The sample was synthesized from pure metals (≥ 99.9 mass%) by arc melting under argon atmosphere and annealed under vacuum at 600 °C for 720 h. Refinement of the profile and structure parameters was performed using the FullProf Suite software package [1].
