Abstract

The two-layer average structure of the high-temperature phase basic Co-rich decagonal Al72.5 Co18.5 Ni9 was determined based on single-crystal x-ray diffraction data. The five-dimensional (5D) structure model was refined in the noncentrosymmetric 5D space group P 10 ̄ m2 (112 parameters, wR=0.123 and R=0.156 for 957 reflections). The close relationship of the model structure with that of W-Al-Co-Ni, a □ 3/2,2/1 □ approximant, is shown.
