In the third Rh site, Rh(3) is bonded to two equivalent Te(6), two equivalent Te(7), and two equivalent Te(8) atoms to form a mixture of distorted corner and face-sharing RhTe6 octahedra. The corner-sharing octahedral tilt angles are 56°. In the fourth Rh site, Rh(4) is bonded in a 4-coordinate geometry to one Rh(1), one Te(1), one Te(2), one Te(4), and one Te(6) atom. In the fifth Rh site, Rh(5) is bonded to one Te(1), one Te(4), one Te(6), one Te(7), and two equivalent Te(8) atoms to form a mixture of distorted corner, edge, and face-sharing RhTe6 octahedra. The corner-sharing octahedral tilt angles are 56°. In the sixth Rh site, Rh(6) is bonded in a 5-coordinate geometry to one Rh(1), one Te(4), one Te(5), one Te(7), and two equivalent Te(2) atoms. There are eight inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted water-like geometry to one Rh(4) and one Rh(5) atom.
