a, Powder XRD pattern of the Au56In28.5Eu15.5 iQC. b–d, Selected-area electron diffraction patterns taken along the 5-fold, 3-fold and 2-fold axes. The τ-scaling rule of intense Bragg spots in b indicates the formation of a primitive iQC. e, Spatial configuration of the R atoms in the structure of the iQC, viewed along a five-fold axis. A single icosahedron and acute rhombohedron units, composed of R elements on the vertices and along the long-body diagonal axis, respectively, are also shown. The R atoms belonging to each unit are shown in different colours for distinction.
