PtGe3 crystallizes in the triclinic P-1 space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Pt(2), one Ge(1), and one Ge(2) atom. The Pt(1)-Pt(2) bond length is 0.58 Å. The Pt(1)-Ge(1) bond length is 2.76 Å. The Pt(1)-Ge(2) bond length is 1.96 Å. In the second Pt site, Pt(2) is bonded in a distorted single-bond geometry to one Pt(1), one Ge(2), one Ge(5), and one Ge(6) atom. The Pt(2)-Ge(2) bond length is 1.90 Å. The Pt(2)-Ge(5) bond length is 2.41 Å. The Pt(2)-Ge(6) bond length is 2.56 Å. There are six inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 4-coordinate geometry to one Pt(1), one Ge(5), and two equivalent Ge(6) atoms. The Ge(1)-Ge(5) bond length is 2.45 Å. There is one shorter (1.88 Å) and one longer (2.63 Å) Ge(1)-Ge(6) bond length. In the second Ge site, Ge(2) is bonded in a 6-coordinate geometry to one Pt(1), one Pt(2), one Ge(4), one Ge(5), and two equivalent Ge(3) atoms. The Ge(2)-Ge(4) bond length is 1.71 Å. The Ge(2)-Ge(5) bond length is 1.81 Å. There is one shorter (1.66 Å) and one longer (1.71 Å) Ge(2)-Ge(3) bond length. In the third Ge site, Ge(3) is bonded in a 1-coordinate geometry to one Ge(3), one Ge(5), two equivalent Ge(2), and two equivalent Ge(4) atoms. The Ge(3)-Ge(3) bond length is 1.36 Å. The Ge(3)-Ge(5) bond length is 1.71 Å. There is one shorter (1.41 Å) and one longer (1.81 Å) Ge(3)-Ge(4) bond length. In the fourth Ge site, Ge(4) is bonded in a 4-coordinate geometry to one Ge(2), one Ge(5), and two equivalent Ge(3) atoms. The Ge(4)-Ge(5) bond length is 1.71 Å. In the fifth Ge site, Ge(5) is bonded in a 5-coordinate geometry to one Pt(2), one Ge(1), one Ge(2), one Ge(3), and one Ge(4) atom. In the sixth Ge site, Ge(6) is bonded in a 3-coordinate geometry to one Pt(2) and two equivalent Ge(1) atoms.
