BaW2Cl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BaW2Cl clusters. Ba(1) is bonded in a 2-coordinate geometry to one W(1) and one Cl(1) atom. The Ba(1)-W(1) bond length is 1.99 Å. The Ba(1)-Cl(1) bond length is 1.43 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a distorted single-bond geometry to one Ba(1) and one W(2) atom. The W(1)-W(2) bond length is 1.44 Å. In the second W site, W(2) is bonded in a 2-coordinate geometry to one W(1) and one Cl(1) atom. The W(2)-Cl(1) bond length is 2.31 Å. Cl(1) is bonded in a distorted single-bond geometry to one Ba(1) and one W(2) atom.
