Pt2Ge crystallizes in the hexagonal P-62m space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 5-coordinate geometry to one Ge(2) and four equivalent Ge(1) atoms. In the second Pt site, Pt(2) is bonded to two equivalent Ge(1) and two equivalent Ge(2) atoms to form a mixture of distorted edge and corner-sharing PtGe4 tetrahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Pt(2) and six equivalent Pt(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Pt(1) and six equivalent Pt(2) atoms.
Pt2Ge crystallizes in the hexagonal P-62m space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 5-coordinate geometry to one Ge(2) and four equivalent Ge(1) atoms. The Pt(1)-Ge(2) bond length is 2.55 Å. All Pt(1)-Ge(1) bond lengths are 2.76 Å. In the second Pt site, Pt(2) is bonded to two equivalent Ge(1) and two equivalent Ge(2) atoms to form a mixture of distorted edge and corner-sharing PtGe4 tetrahedra. Both Pt(2)-Ge(1) bond lengths are 2.44 Å. Both Pt(2)-Ge(2) bond lengths are 2.60 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Pt(2) and six equivalent Pt(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Pt(1) and six equivalent Pt(2) atoms.
