A new ternary compound with the BGa 8 Ir 4 structure type in the Al–Au–Ir system

Following the recent determination of the Al 3 AuIr structure, a new ternary phase has been identified in the Al–Au–Ir phase diagram. It has a chemical composition Al 9 (Au;Ir) 4 with an apparently low gold content. Its crystal structure has been determined with single-crystal X-ray diffraction. The...

Description
Summary:Following the recent determination of the Al 3 AuIr structure, a new ternary phase has been identified in the Al–Au–Ir phase diagram. It has a chemical composition Al 9 (Au;Ir) 4 with an apparently low gold content. Its crystal structure has been determined with single-crystal X-ray diffraction. The new compound crystallizes in the tetragonal crystal system and has been successfully solved in space group I 4 1 / acd (Pearson symbol tI 104) with lattice parameters a = 8.6339 (2) and c = 21.8874 (7) Å. Atomic environments are described as well as similarities with the BGa 8 Ir 4 compound.
