Y Bi W W
YW2Bi crystallizes in the triclinic P1 space group. Y(1) is bonded in a single-bond geometry to one W(1) and two equivalent W(2) atoms. The Y(1)-W(1) bond length is 0.33 Å. There is one shorter (1.58 Å) and one longer (3.53 Å) Y(1)-W(2) bond length. There are two inequivalent W sites. In the first W site, W(1) is bonded in a single-bond geometry to one Y(1), one W(2), and one Bi(1) atom. The W(1)-W(2) bond length is 1.38 Å. The W(1)-Bi(1) bond length is 1.38 Å. In the second W site, W(2) is bonded in a 6-coordinate geometry to two equivalent Y(1), one W(1), and three equivalent Bi(1) atoms. There is one shorter (1.87 Å) and two longer (3.51 Å) W(2)-Bi(1) bond lengths. Bi(1) is bonded in a distorted single-bond geometry to one W(1) and three equivalent W(2) atoms.
