WTlTlB crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TlB clusters and two WTl clusters. In each TlB cluster, Tl(2) is bonded in a single-bond geometry to one B(1) atom. The Tl(2)-B(1) bond length is 1.61 Å. B(1) is bonded in a 1-coordinate geometry to one Tl(2) atom. In each WTl cluster, W(1) is bonded in a single-bond geometry to one Tl(1) atom. The W(1)-Tl(1) bond length is 0.29 Å. Tl(1) is bonded in a single-bond geometry to one W(1) atom.
