Abstract. Samples prepared across the Y bCu5-xAux solid solution system remain cubic AuBe5-type up to x = 1.8. As the Au concentration x is increased, the Au atoms first replace the Cu atoms on the 4c sites of the F\bar {4} 3 m space group until the sites are fully occupied, and then replace atoms on the 16e sites until the structure becomes unstable. The composition at x = 1 is at the crossover between two kinds of disordered sublattices and the ground state properties follow a non-monotonic behaviour through x = 1.
