Materials Data on SmRh3C by Materials Project
SmRh3C is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sm is bonded to twelve equivalent Rh atoms to form SmRh12 cuboctahedra that share corners with twelve equivalent SmRh12 cuboctahedra, faces with six equivalent SmRh12 cuboctahedra, and faces with eight equivalent CRh6 octahedra. All Sm–Rh bond lengths are 2.98 Å. Rh is bonded to four equivalent Sm and two equivalent C atoms to form a mixture of distorted corner, edge, and face-sharing RhSm4C2 octahedra. The corner-sharing octahedra tilt angles range from 0–60°. Both Rh–C bond lengths are 2.11 Å. C is bonded to six equivalent Rh atoms to form CRh6 octahedra that share corners with six equivalent CRh6 octahedra and faces with eight equivalent SmRh12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°.
