Materials Data on Te16Rh9 by Materials Project
Rh9Te16 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are five inequivalent Rh+3.56+ sites. In the first Rh+3.56+ site, Rh+3.56+ is bonded to six Te2- atoms to form a mixture of edge and corner-sharing RhTe6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Rh–Te bond distances ranging from 2.65–2.72 Å. In the second Rh+3.56+ site, Rh+3.56+ is bonded to six Te2- atoms to form a mixture of edge and corner-sharing RhTe6 octahedra. The corner-sharing octahedra tilt angles range from 51–53°. There are a spread of Rh–Te bond distances ranging from 2.66–2.69 Å. In the third Rh+3.56+ site, Rh+3.56+ is bonded to six Te2- atoms to form a mixture of edge and corner-sharing RhTe6 octahedra. The corner-sharing octahedra tilt angles range from 51–53°. There are a spread of Rh–Te bond distances ranging from 2.65–2.71 Å. In the fourth Rh+3.56+ site, Rh+3.56+ is bonded to six Te2- atoms to form a mixture of edge and face-sharing RhTe6 octahedra. There are a spread of Rh–Te bond distances ranging from 2.66–2.74 Å. In the fifth Rh+3.56+ site, Rh+3.56+ is bonded to six Te2- atoms to form a mixture of face and corner-sharing RhTe6 octahedra. The corner-sharing octahedra tilt angles range from 51–53°. There are a spread of Rh–Te bond distances ranging from 2.72–2.77 Å. There are eight inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 4-coordinate geometry to four Rh+3.56+ atoms. In the second Te2- site, Te2- is bonded in a 4-coordinate geometry to four Rh+3.56+ atoms.
