Cs3Mo15Te17 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 9-coordinate geometry to nine Te2- atoms. There are a spread of Cs–Te bond distances ranging from 3.88–4.09 Å. In the second Cs1+ site, Cs1+ is bonded in a 11-coordinate geometry to eleven Te2- atoms. There are a spread of Cs–Te bond distances ranging from 3.89–4.09 Å. There are three inequivalent Mo+2.07+ sites. In the first Mo+2.07+ site, Mo+2.07+ is bonded in a see-saw-like geometry to four Te2- atoms. There are a spread of Mo–Te bond distances ranging from 2.79–2.89 Å. In the second Mo+2.07+ site, Mo+2.07+ is bonded in a see-saw-like geometry to four Te2- atoms. There are a spread of Mo–Te bond distances ranging from 2.83–2.89 Å. In the third Mo+2.07+ site, Mo+2.07+ is bonded to five Te2- atoms to form a mixture of corner and edge-sharing MoTe5 square pyramids. There are a spread of Mo–Te bond distances ranging from 2.74–2.92 Å. There are four inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 6-coordinate geometry to two Cs1+ and four Mo+2.07+ atoms. In the second Te2- site, Te2- is bonded in a 5-coordinate geometry to one Cs1+ and four Mo+2.07+ atoms. In the third Te2- site, Te2- is bonded in a 7-coordinate geometry to three Cs1+ and four Mo+2.07+ atoms. In the fourth Te2- site, Te2- is bonded in a 7-coordinate geometry to one Cs1+ and three equivalent Mo+2.07+ atoms.
