Pt3Ge crystallizes in the monoclinic C2/m space group. There are three inequivalent Pt sites. In the first Pt site, Pt(3) is bonded in a distorted water-like geometry to four equivalent Pt(1) and two equivalent Ge(1) atoms. In the second Pt site, Pt(1) is bonded to four equivalent Pt(2), four equivalent Pt(3), and four equivalent Ge(1) atoms to form a mixture of distorted corner and face-sharing PtGe4Pt8 cuboctahedra. In the third Pt site, Pt(2) is bonded in a distorted water-like geometry to four equivalent Pt(1) and two equivalent Ge(1) atoms. Ge(1) is bonded in a 8-coordinate geometry to two equivalent Pt(2), two equivalent Pt(3), and four equivalent Pt(1) atoms.
Pt3Ge crystallizes in the monoclinic C2/m space group. There are three inequivalent Pt sites. In the first Pt site, Pt(3) is bonded in a distorted water-like geometry to four equivalent Pt(1) and two equivalent Ge(1) atoms. There are two shorter (2.83 Å) and two longer (2.84 Å) Pt(3)-Pt(1) bond lengths. Both Pt(3)-Ge(1) bond lengths are 2.50 Å. In the second Pt site, Pt(1) is bonded to four equivalent Pt(2), four equivalent Pt(3), and four equivalent Ge(1) atoms to form a mixture of distorted corner and face-sharing PtGe4Pt8 cuboctahedra. All Pt(1)-Pt(2) bond lengths are 2.83 Å. There are two shorter (2.76 Å) and two longer (2.78 Å) Pt(1)-Ge(1) bond lengths. In the third Pt site, Pt(2) is bonded in a distorted water-like geometry to four equivalent Pt(1) and two equivalent Ge(1) atoms. There is one shorter (2.49 Å) and one longer (2.50 Å) Pt(2)-Ge(1) bond length. Ge(1) is bonded in a 8-coordinate geometry to two equivalent Pt(2), two equivalent Pt(3), and four equivalent Pt(1) atoms.
