Cs4TeSe15 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are four inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 10-coordinate geometry to ten Se+0.53- atoms. There are a spread of Cs–Se bond distances ranging from 3.67–4.27 Å. In the second Cs1+ site, Cs1+ is bonded in a 2-coordinate geometry to eight Se+0.53- atoms. There are a spread of Cs–Se bond distances ranging from 3.69–4.28 Å. In the third Cs1+ site, Cs1+ is bonded in a 8-coordinate geometry to ten Se+0.53- atoms. There are a spread of Cs–Se bond distances ranging from 3.66–4.32 Å. In the fourth Cs1+ site, Cs1+ is bonded in a 2-coordinate geometry to ten Se+0.53- atoms. There are a spread of Cs–Se bond distances ranging from 3.69–4.10 Å. Te4+ is bonded in a square co-planar geometry to four Se+0.53- atoms. There are two shorter (2.74 Å) and two longer (2.97 Å) Te–Se bond lengths. There are eight inequivalent Se+0.53- sites. In the first Se+0.53- site, Se+0.53- is bonded in a 5-coordinate geometry to three Cs1+ and two Se+0.53- atoms. Both Se–Se bond lengths are 2.38 Å. In the second Se+0.53- site, Se+0.53- is bonded in a 3-coordinate geometry to two equivalent Cs1+ and two equivalent Se+0.53- atoms. Both Se–Se bond lengths are 2.39 Å. In the third Se+0.53- site, Se+0.53- is bonded in a 1-coordinate geometry to three Cs1+, one Te4+, and two Se+0.53- atoms. There are one shorter (2.38 Å) and one longer (3.45 Å) Se–Se bond lengths. In the fourth Se+0.53- site, Se+0.53- is bonded in a 6-coordinate geometry to four Cs1+ and two Se+0.53- atoms. The Se–Se bond length is 3.17 Å. In the fifth Se+0.53- site, Se+0.53- is bonded in a 3-coordinate geometry to two Cs1+ and two Se+0.53- atoms. The Se–Se bond length is 2.41 Å. In the sixth Se+0.53- site, Se+0.53- is bonded in a 1-coordinate geometry to two Cs1+, one Te4+, and two Se+0.53- atoms. The Se–Se bond length is 2.41 Å. In the seventh Se+0.53- site, Se+0.53- is bonded in a 4-coordinate geometry to two Cs1+ and two Se+0.53- atoms. In the eighth Se+0.53- site, Se+0.53- is bonded in a 3-coordinate geometry to two Cs1+ and three Se+0.53- atoms.
