W2MoBi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two W2MoBi clusters. W(1) is bonded in a 2-coordinate geometry to one Mo(1) and one Bi(1) atom. The W(1)-Mo(1) bond length is 1.84 Å. The W(1)-Bi(1) bond length is 1.84 Å. Mo(1) is bonded in a 2-coordinate geometry to two equivalent W(1) atoms. Bi(1) is bonded in a 2-coordinate geometry to two equivalent W(1) atoms.
