KBTe2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KBTe2 clusters. K(1) is bonded in a single-bond geometry to one B(1) atom. The K(1)-B(1) bond length is 1.11 Å. B(1) is bonded in a single-bond geometry to one K(1) and one Te(1) atom. The B(1)-Te(1) bond length is 2.14 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 2-coordinate geometry to one B(1) and one Te(2) atom. The Te(1)-Te(2) bond length is 1.69 Å. In the second Te site, Te(2) is bonded in a single-bond geometry to one Te(1) atom.
