RePtGe2 crystallizes in the trigonal R3m space group. Re(1) is bonded in a 1-coordinate geometry to three equivalent Pt(1) and one Ge(2) atom. All Re(1)-Pt(1) bond lengths are 2.73 Å. The Re(1)-Ge(2) bond length is 2.05 Å. Pt(1) is bonded in a 11-coordinate geometry to three equivalent Re(1), four equivalent Ge(1), and four equivalent Ge(2) atoms. There is one shorter (2.05 Å) and three longer (3.07 Å) Pt(1)-Ge(1) bond lengths. There is one shorter (2.45 Å) and three longer (2.88 Å) Pt(1)-Ge(2) bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a distorted single-bond geometry to four equivalent Pt(1) atoms. In the second Ge site, Ge(2) is bonded in a distorted linear geometry to one Re(1) and four equivalent Pt(1) atoms.
