Sb As As Rh
RhSbAs2 crystallizes in the monoclinic Cm space group. Rh(1) is bonded in a 6-coordinate geometry to two equivalent Sb(1) and four equivalent As(1) atoms. There is one shorter (2.18 Å) and one longer (2.65 Å) Rh(1)-Sb(1) bond length. There are two shorter (2.28 Å) and two longer (2.89 Å) Rh(1)-As(1) bond lengths. Sb(1) is bonded in a distorted water-like geometry to two equivalent Rh(1) and two equivalent As(1) atoms. Both Sb(1)-As(1) bond lengths are 1.29 Å. As(1) is bonded in a single-bond geometry to two equivalent Rh(1) and one Sb(1) atom.
