K5Te3 crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 4-coordinate geometry to two equivalent K1+ and four equivalent Te+1.67- atoms. Both K–K bond lengths are 3.25 Å. All K–Te bond lengths are 3.45 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six Te+1.67- atoms. There are a spread of K–Te bond distances ranging from 3.66–3.82 Å. In the third K1+ site, K1+ is bonded in a 6-coordinate geometry to six Te+1.67- atoms. There are a spread of K–Te bond distances ranging from 3.64–3.82 Å. There are two inequivalent Te+1.67- sites. In the first Te+1.67- site, Te+1.67- is bonded in a 10-coordinate geometry to ten K1+ atoms. In the second Te+1.67- site, Te+1.67- is bonded in a 10-coordinate geometry to eight K1+ and one Te+1.67- atom. The Te–Te bond length is 2.85 Å.
