Te Te Rh Se
RhTe2Se is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RhTe2Se clusters. Rh(1) is bonded in a 3-coordinate geometry to two equivalent Te(1) and one Se(1) atom. Both Rh(1)-Te(1) bond lengths are 1.42 Å. The Rh(1)-Se(1) bond length is 1.43 Å. Te(1) is bonded in a 3-coordinate geometry to one Rh(1), one Te(1), and one Se(1) atom. The Te(1)-Te(1) bond length is 1.43 Å. The Te(1)-Se(1) bond length is 1.42 Å. Se(1) is bonded in a 3-coordinate geometry to one Rh(1) and two equivalent Te(1) atoms.
