Materials Data on CsTe7Mo6 by Materials Project
CsMo6Te7 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Cs1+ is bonded in a 10-coordinate geometry to ten Te2- atoms. There are a spread of Cs–Te bond distances ranging from 3.87–4.20 Å. There are two inequivalent Mo+2.17+ sites. In the first Mo+2.17+ site, Mo+2.17+ 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. In the second Mo+2.17+ site, Mo+2.17+ is bonded in a see-saw-like geometry to four Te2- atoms. There are a spread of Mo–Te bond distances ranging from 2.79–2.88 Å. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 5-coordinate geometry to one Cs1+ and four Mo+2.17+ atoms. In the second Te2- site, Te2- is bonded in a 6-coordinate geometry to two equivalent Cs1+ and four Mo+2.17+ atoms. In the third Te2- site, Te2- is bonded in a 7-coordinate geometry to one Cs1+ and three equivalent Mo+2.17+ atoms.
