A bcc phase (a=1.510–1.519nm), possibly isostructural with Cd6RE, exists in Ag42In42RE16alloys, where RE=Gd, Tb, Dy, Ho, Er, Tm, and Lu. In Ag42In42Yb16, however, a C-centered monoclinic phase (a=2.60nm, b=1.48nm, c=2.63nm, β≈108°) coexists with the icosahedral quasicrystal (IQC). All these crystalline phases show local pseudo-icosahedral symmetry.
