Li As As Rh
LiRhAs2 crystallizes in the orthorhombic Pmm2 space group. Li(1) is bonded in a water-like geometry to two equivalent As(1) atoms. Both Li(1)-As(1) bond lengths are 0.59 Å. Rh(1) is bonded to four equivalent Rh(1) and two equivalent As(1) atoms to form a mixture of corner and edge-sharing RhAs2Rh4 octahedra. The corner-sharing octahedra are not tilted. All Rh(1)-Rh(1) bond lengths are 3.03 Å. Both Rh(1)-As(1) bond lengths are 3.06 Å. As(1) is bonded in a single-bond geometry to one Li(1) and one Rh(1) atom.
