Gd(PdGe)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Gd is bonded in a 4-coordinate geometry to eight equivalent Pd and eight equivalent Ge atoms. There are six shorter (3.34 Å) and two longer (3.35 Å) Gd–Pd bond lengths. There are four shorter (3.29 Å) and four longer (3.30 Å) Gd–Ge bond lengths. Pd is bonded in a 4-coordinate geometry to four equivalent Gd and four equivalent Ge atoms. All Pd–Ge bond lengths are 2.53 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Gd, four equivalent Pd, and one Ge atom. The Ge–Ge bond length is 2.47 Å.
