The material structure described by Pr2Rh3Si crystallizes in the trigonal R-3m space group. Pr(1) is bonded in a 3-coordinate geometry to nine equivalent Rh(1) atoms. Rh(1) is bonded to six equivalent Pr(1), four equivalent Rh(1), and two equivalent Si(1) atoms to form distorted RhPr6Si2Rh4 cuboctahedra that share corners with four equivalent Si(1)Rh6 cuboctahedra, corners with fourteen equivalent Rh(1)Pr6Si2Rh4 cuboctahedra, edges with two equivalent Si(1)Rh6 cuboctahedra, edges with six equivalent Rh(1)Pr6Si2Rh4 cuboctahedra, and faces with twelve equivalent Rh(1)Pr6Si2Rh4 cuboctahedra. Si(1) is bonded to six equivalent Rh(1) atoms to form distorted SiRh6 cuboctahedra that share corners with six equivalent Si(1)Rh6 cuboctahedra, corners with twelve equivalent Rh(1)Pr6Si2Rh4 cuboctahedra, and edges with six equivalent Rh(1)Pr6Si2Rh4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
