WBi3Cl is alpha Po structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three WBi3Cl clusters. W(1) is bonded in a 3-coordinate geometry to three equivalent Bi(1) atoms. All W(1)-Bi(1) bond lengths are 2.44 Å. Bi(1) is bonded in a distorted single-bond geometry to one W(1) and one Cl(1) atom. The Bi(1)-Cl(1) bond length is 1.72 Å. Cl(1) is bonded in a distorted T-shaped geometry to three equivalent Bi(1) atoms.
