The paper presents crystal structure data for three samples from the partially ordered solid solution HfPt xPd1-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 P2c; Z = 6; Pearson symbol hP18). Unit cell parameters for x = 0.24 are: a = 7.1502(2) Å and c = 6.9106(3) Å. Both a and c change approximately linearly with increasing Pt content.
