PuRh3C is (Cubic) Perovskite structured and crystallizes in the tetragonal P4/mmm space group. Pu(1) is bonded to four equivalent Rh(2) and eight equivalent Rh(1) atoms to form PuRh12 cuboctahedra that share corners with twelve equivalent Pu(1)Rh12 cuboctahedra, faces with six equivalent Pu(1)Rh12 cuboctahedra, and faces with eight equivalent C(1)Rh6 octahedra. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to four equivalent Pu(1) and two equivalent C(1) atoms to form a mixture of distorted edge, corner, and face-sharing RhPu4C2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°. In the second Rh site, Rh(2) is bonded to four equivalent Pu(1) and two equivalent C(1) atoms to form a mixture of distorted edge, corner, and face-sharing RhPu4C2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°. C(1) is bonded to two equivalent Rh(2) and four equivalent Rh(1) atoms to form CRh6 octahedra that share corners with six equivalent C(1)Rh6 octahedra and faces with eight equivalent Pu(1)Rh12 cuboctahedra. The corner-sharing octahedra are not tilted.
