Materials Data on Te16Rh11 by Materials Project
Rh11Te16 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are six inequivalent Rh sites. In the first Rh site, Rh is bonded in a 7-coordinate geometry to two Rh and five Te atoms. There are one shorter (2.84 Å) and one longer (2.85 Å) Rh–Rh bond lengths. There are a spread of Rh–Te bond distances ranging from 2.65–2.89 Å. In the second Rh site, Rh is bonded in a 5-coordinate geometry to five Te atoms. There are a spread of Rh–Te bond distances ranging from 2.57–2.79 Å. In the third Rh site, Rh is bonded to six Te atoms to form a mixture of distorted corner and face-sharing RhTe6 octahedra. The corner-sharing octahedral tilt angles are 56°. There are a spread of Rh–Te bond distances ranging from 2.62–2.85 Å. In the fourth Rh site, Rh is bonded in a 4-coordinate geometry to one Rh and four Te atoms. There are a spread of Rh–Te bond distances ranging from 2.58–2.73 Å. In the fifth Rh site, Rh is bonded to six Te atoms to form a mixture of distorted corner, edge, and face-sharing RhTe6 octahedra. The corner-sharing octahedral tilt angles are 56°. There are a spread of Rh–Te bond distances ranging from 2.64–3.04 Å. In the sixth Rh site, Rh is bonded in a 5-coordinate geometry to one Rh and five Te atoms. There are a spread of Rh–Te bond distances ranging from 2.61–2.81 Å. There are eight inequivalent Te sites. In the first Te site, Te is bonded in a distorted water-like geometry to two Rh atoms. In the second Te site, Te is bonded in a 5-coordinate geometry to five Rh atoms. In the third Te site, Te is bonded in a 3-coordinate geometry to three Rh atoms. In the fourth Te site, Te is bonded in a distorted T-shaped geometry to three Rh atoms. In the fifth Te site, Te is bonded in a 4-coordinate geometry to four Rh atoms. In the sixth Te site, Te is bonded in a 3-coordinate geometry to three Rh atoms. In the seventh Te site, Te is bonded in a 4-coordinate geometry to four Rh atoms. In the eighth Te site, Te is bonded to four Rh atoms to form a mixture of distorted corner and edge-sharing TeRh4 trigonal pyramids.
