Ge2Pt3 crystallizes in the orthorhombic Cmcm 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 in a 5-coordinate geometry to two equivalent Ge(1) and three equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a body-centered cubic geometry to four equivalent Pt(1) and four equivalent Pt(2) atoms. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to one Pt(1) and six equivalent Pt(2) atoms.
Ge2Pt3 crystallizes in the orthorhombic Cmcm 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 2.56 Å. All Pt(1)-Ge(1) bond lengths are 2.61 Å. In the second Pt site, Pt(2) is bonded in a 5-coordinate geometry to two equivalent Ge(1) and three equivalent Ge(2) atoms. Both Pt(2)-Ge(1) bond lengths are 2.66 Å. All Pt(2)-Ge(2) bond lengths are 2.56 Å. There are two inequivalent Ge sites.
