K2NaTe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two K2NaTe clusters. There are two inequivalent K sites. In the first K site, K(1) is bonded in a distorted single-bond geometry to one K(2) atom. The K(1)-K(2) bond length is 0.86 Å. In the second K site, K(2) is bonded in a 2-coordinate geometry to one K(1) and one Na(1) atom. The K(2)-Na(1) bond length is 2.96 Å. Na(1) is bonded in a single-bond geometry to one K(2) and one Te(1) atom. The Na(1)-Te(1) bond length is 1.43 Å. Te(1) is bonded in a single-bond geometry to one Na(1) atom.
