Bi Pt W W
W2PtBi crystallizes in the triclinic P1 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a distorted rectangular see-saw-like geometry to one W(2), one Pt(1), and two equivalent Bi(1) atoms. The W(1)-W(2) bond length is 2.15 Å. The W(1)-Pt(1) bond length is 2.39 Å. There is one shorter (2.45 Å) and one longer (2.75 Å) W(1)-Bi(1) bond length. In the second W site, W(2) is bonded in a single-bond geometry to one W(1), one Pt(1), and two equivalent Bi(1) atoms. The W(2)-Pt(1) bond length is 0.54 Å. There is one shorter (3.09 Å) and one longer (3.56 Å) W(2)-Bi(1) bond length. Pt(1) is bonded in a distorted single-bond geometry to one W(1), one W(2), and one Bi(1) atom. The Pt(1)-Bi(1) bond length is 2.91 Å. Bi(1) is bonded in a 7-coordinate geometry to two equivalent W(1), two equivalent W(2), one Pt(1), and two equivalent Bi(1) atoms. Both Bi(1)-Bi(1) bond lengths are 3.18 Å.
