abstract = {A model for the pseudodecagonal approximant PD4 in the
Al-Co-Ni system was deduced from single crystal X-ray
diffraction data. The space group is Bbmm with a = 101.3, b
= 32.1 and c = 4.1 angstrom. Atomic positions of 133 unique
atoms in the unit cell with a reasonable geometry were found
by direct methods and the difference Fourier syntheses. The
obtained structure model is in good agreement with
high-resolution electron microscopy images of PD4. Diffuse
scattering observed along the a* direction in the hkl layers
with l = 1/2, 3/2 etc. indicates a superstructure with a
doubling of the periodicity along the c-axis and a lamellar
disorder along the a-axis. If this diffuse scattering is
taken into account, c = 8.2 angstrom.},
