Pt2SnGe crystallizes in the monoclinic Pm space group. Pt(1) is bonded in a 4-coordinate geometry to one Pt(1), two equivalent Sn(1), and one Ge(1) atom. The Pt(1)-Pt(1) bond length is 1.35 Å. There is one shorter (2.37 Å) and one longer (2.88 Å) Pt(1)-Sn(1) bond length. The Pt(1)-Ge(1) bond length is 2.89 Å. Sn(1) is bonded in a 5-coordinate geometry to four equivalent Pt(1) and one Ge(1) atom. The Sn(1)-Ge(1) bond length is 1.39 Å. Ge(1) is bonded in a distorted single-bond geometry to two equivalent Pt(1) and one Sn(1) atom.
