abstract = {The crystal structure of the novel Al77Rh15Ru8 phase (which
is an approximant of decagonal quasicrystals) was determined
using modern direct methods (MDM) applied to automated
electron diffraction tomography (ADT) data. The Al77Rh15Ru8
E-phase is orthorhombic [Pbma, a = 23.40 (5), b = 16.20 (4)
and c = 20.00 (5) Å] and has one of the most complicated
intermetallic structures solved solely by electron
diffraction methods. Its structural model consists of 78
unique atomic positions in the unit cell (19 Rh/Ru and 59
Al). Precession electron diffraction (PED) patterns and
high-resolution electron microscopy (HRTEM) images were used
for the validation of the proposed atomic model. The
structure of the E-phase is described using hierarchical
packing of polyhedra and a single type of tiling in the form
of a parallelogram. Based on this description, the structure
of the E-phase is compared with that of the [epsilon]6-phase
formed in Al-Rh-Ru at close compositions},
