KNaTe2 crystallizes in the triclinic P1 space group. K(1) is bonded in a single-bond geometry to one Te(2) and three equivalent Te(1) atoms. The K(1)-Te(2) bond length is 1.91 Å. There is one shorter (2.67 Å) and two longer (3.46 Å) K(1)-Te(1) bond lengths. Na(1) is bonded in a 1-coordinate geometry to one Te(1) and one Te(2) atom. The Na(1)-Te(1) bond length is 3.22 Å. The Na(1)-Te(2) bond length is 2.34 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 5-coordinate geometry to three equivalent K(1), one Na(1), and one Te(2) atom. The Te(1)-Te(2) bond length is 1.91 Å. In the second Te site, Te(2) is bonded in a 2-coordinate geometry to one K(1), one Na(1), and one Te(1) atom.
