Abstract
A high-angle annular dark field scanning transmission electron microscopy study of the intermetallic compound Al<sub>74</sub>Cr<sub>15</sub>Fe<sub>11</sub> reveals a quasiperiodic structure significantly differing from the ones known so far. In contrast to the common quasi-unit-cells based on Gummelt decagons, the present structure is related to a covering formed by Lück decagons, which can also be described by a Hexagon-Bow-Tie tiling.
