Cr Bi W W
W2CrBi crystallizes in the monoclinic Cm space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a single-bond geometry to one Cr(1) and one Bi(1) atom. The W(1)-Cr(1) bond length is 1.27 Å. The W(1)-Bi(1) bond length is 3.18 Å. In the second W site, W(2) is bonded in a single-bond geometry to one Cr(1) and one Bi(1) atom. The W(2)-Cr(1) bond length is 1.52 Å. The W(2)-Bi(1) bond length is 3.18 Å. Cr(1) is bonded in a linear geometry to one W(1) and one W(2) atom. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to one W(1); one W(2); and six Bi(1,1) atoms to form a mixture of distorted corner and edge-sharing BiBi6W2 hexagonal bipyramids. All Bi(1)-Bi(1,1) bond lengths are 3.05 Å. In the second Bi site, Bi(1) is bonded to one W(1); one W(2); and six Bi(1,1) atoms to form a mixture of distorted corner and edge-sharing BiBi6W2 hexagonal bipyramids. The Bi(1)-W(1) bond length is 3.18 Å. The Bi(1)-W(2) bond length is 3.18 Å. Both Bi(1)-Bi(1) bond lengths are 3.05 Å.
