All Pd–Pd bond lengths are 2.75 Å.
HfRuGe crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Hf is bonded in a 11-coordinate geometry to six equivalent Ru and five Ge atoms. There are two shorter (2.95 Å) and four longer (3.09 Å) Hf–Ru bond lengths. There are four shorter (2.77 Å) and one longer (2.81 Å) Hf–Ge bond lengths. Ru is bonded in a 12-coordinate geometry to six equivalent Hf and four Ge atoms. There are two shorter (2.51 Å) and two longer (2.59 Å) Ru–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six equivalent Hf and three equivalent Ru atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to three equivalent Hf and six equivalent Ru atoms.
CrRu crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional.
