Quasicrystal approximant Ho13Zn 58 + δ (δ ≈ 0.6) : An incommensurate modulated tunnel structure
(2007) In Philosophical Magazine 87(18-21). p.2693-2699- Abstract
In a systematic study of the binary quasicrystal approximants RE13Zn58 (RE = rare earth elements) system, single crystals of Ho13Zn58 + have been prepared. It is unique among family members of the RE13Zn58 system in that it shows a modulated superstructure ordering. Satellite reflections observed in single crystal X-ray diffraction pattern indicate the presence of a one-dimensional lattice distortion. The modulated structure has been solved and refined from X-ray data using the superspace group approach. The Ho13Zn58 + structure can be described in the (3 + 1)-dimensional superspace group Pc21n(00)s0s with lattice parameters a = 24.6481(7) , b = 14.2484(4) , c = 14.0153(3) and a modulation vector q = (0, 0.741, 0).

The crystal structure is closely related to those of other RE13Zn58 compounds, comprising hexagon-shaped tunnels made up of rare earth-centred Zn polyhedra. All atoms in the structure are affected by a displacive modulation, but one set of Zn atoms are very strongly affected and display an almost composite behaviour with regard to the rest of the structure.
