KTlTe2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KTlTe2 clusters. K(1) is bonded in a single-bond geometry to one Tl(1) and two equivalent Te(1) atoms. The K(1)-Tl(1) bond length is 0.80 Å. Both K(1)-Te(1) bond lengths are 2.26 Å. Tl(1) is bonded in a single-bond geometry to one K(1) atom. Te(1) is bonded in a 1-coordinate geometry to one K(1) atom.
