The paper presents crystal structure data for
three samples from the partially ordered solid solution HfPtxPd1-xGa, with x ranging from 0 to 1. Their crystal structures were determined by
Rietveld refinements of powder X-ray diffraction patterns. The phase
crystallizes with the HfRhSn type of structure (space group P-62c; Z = 6;
Pearson symbol hP18). Unit cell parameters for x = 0.24
are: a = 7.1502(2) nm and c = 6.9106(3) nm. Both a and c change
approximately linearly with increasing Pt content.
Projection of the unit cell on the xy plane and coordination polyhedra of
the atoms for the HfPtxPd1‑xGa solid solution.
