Abstract

The structure of Co-rich decagonal Al72.5Co18.5Ni9 has been determined by single crystal X-ray diffraction methods. This is the only modification with four-layer periodicity showing sharp Bragg reflections in all reciprocal space layers. The quasilattice parameters are a1-4 = 4.464(1) and a5 = 8.137(3) ; the Laue group is 10/mmm. Structure solution was performed by the 5D 'charge-flipping method'. Due to pseudosymmetry, only a structure model averaged over a two-layer period (4.068 ) could be obtained.
