Sr Bi Rh Rh Rh
SrRh3Bi is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Sr(1) is bonded to twelve equivalent Rh(1) atoms to form SrRh12 cuboctahedra that share corners with twelve equivalent Sr(1)Rh12 cuboctahedra, faces with six equivalent Sr(1)Rh12 cuboctahedra, and faces with eight equivalent Bi(1)Rh6 octahedra. There are a spread of Sr(1)-Rh(1) bond distances ranging from 3.44-3.68 Å. Rh(1) is bonded to four equivalent Sr(1) and two equivalent Bi(1) atoms to form a mixture of distorted face, edge, and corner-sharing RhSr4Bi2 octahedra. The corner-sharing octahedral tilt angles range from 0-61°. There is one shorter (2.43 Å) and one longer (2.60 Å) Rh(1)-Bi(1) bond length. Bi(1) is bonded to six equivalent Rh(1) atoms to form BiRh6 octahedra that share corners with six equivalent Bi(1)Rh6 octahedra and faces with eight equivalent Sr(1)Rh12 cuboctahedra. The corner-sharing octahedra are not tilted.
