W2TlGe is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two W2TlGe clusters. W(1) is bonded in a distorted trigonal planar geometry to one W(1), one Tl(1), and one Ge(1) atom. The W(1)-W(1) bond length is 0.36 Å. The W(1)-Tl(1) bond length is 0.75 Å. The W(1)-Ge(1) bond length is 0.37 Å. Tl(1) is bonded in a 2-coordinate geometry to two equivalent W(1) atoms. Ge(1) is bonded in a 2-coordinate geometry to two equivalent W(1) atoms.
