The structure refinements of icosahedral Al-Cu-Fe (i-Al-Cu-Fe) and i-Al-Cu-Ru quasicrystals were performed by using 6-dimensional cluster models and synchrotron radiation data. The structures were proved to be iso-structural to those of i-Al-Pd-Mn and i-Al-Pd-Re which were determined recently. They consist of two 20clusters, one of which is similar to the cluster in the Al-Pd-Mn-Si 2/1 approximant, and two Mackay-like clusters. This structure includes additional inter-penetrated Mackay-like clusters, which are parts of 20clusters.
