Materials Data on Te2Rh3 by Materials Project

Rh3Te2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 5-coordinate geometry to five Te atoms. There are one shorter (2.66 Å) and four longer (2.75 Å) Rh–Te bond lengths. In the second Rh site, Rh is bonded in a 5-coordinate geometry to five Te atoms. There are three shorter (2.66 Å) and two longer (2.80 Å) Rh–Te bond lengths. There are two inequivalent Te sites. In the first Te site, Te is bonded in a body-centered cubic geometry to eight Rh atoms. In the second Te site, Te is bonded in a 7-coordinate geometry to seven Rh atoms.

Materials Data on TeRh by Materials Project

RhTe crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Rh is bonded to two equivalent Rh and six equivalent Te atoms to form a mixture of distorted edge, corner, and face-sharing RhTe6Rh2 octahedra. The corner-sharing octahedra tilt angles range from 0–51°. Both Rh–Rh bond lengths are 2.86 Å. All Rh–Te bond lengths are 2.75 Å. Te is bonded in a 6-coordinate geometry to six equivalent Rh atoms.
