Abstract: A mixture with the initial chemical composition Al 59 Cr 21 Fe 10 Si 10 was subjected to high-pressure sintering, resulting in the unexpected synthesis of an intermetallic compound with the composition Al 48.18 Cr 22.78 Fe 4.04 Si 3 , which adopts the Cr 0.88 Fe 0.12 Ga structure type in the space group R 3 m . Structural analysis indicates that Al, Cr and Fe jointly occupy a special position (Wyckoff site 18 h ), with refined site occupancy factors of 0.676 (6), 0.17 (2) and 0.16 (2), respectively. Cr and Fe share another special position (Wyckoff site 3 b ), with refined site occupancy factors of 0.60 (6) and 0.40 (6), respectively. Other atoms in the crystal (Al and Si) fully occupy their sites.
