The ternary aluminide
Zr6Cu4Al3 was prepared by arc melting. Its
crystal structure was studied by X-ray powder diffraction for the first time.
The above mentioned intermetallic compound
crystallizes with the rhombohedral W6Fe7
structure type (space group R-3m, Pearson symbol hR39, Z = 3). Isostructural phases were observed in the systems Hf–Cu–Al, Nb–Cu–Al, Ta–Cu–Al, Zr–Ag–Al, and Hf–Ag–Al.
