WB2Bi crystallizes in the triclinic P1 space group. W(1) is bonded in a 2-coordinate geometry to one B(1), two equivalent B(2), and one Bi(1) atom. The W(1)-B(1) bond length is 2.24 Å. There is one shorter (2.24 Å) and one longer (3.05 Å) W(1)-B(2) bond length. The W(1)-Bi(1) bond length is 1.83 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 3-coordinate geometry to one W(1), one B(2), and two equivalent Bi(1) atoms. The B(1)-B(2) bond length is 2.13 Å. There is one shorter (1.60 Å) and one longer (1.85 Å) B(1)-Bi(1) bond length. In the second B site, B(2) is bonded in a 4-coordinate geometry to two equivalent W(1), one B(1), and one Bi(1) atom. The B(2)-Bi(1) bond length is 1.60 Å. Bi(1) is bonded in a 4-coordinate geometry to one W(1), one B(2), and two equivalent B(1) atoms.
