The structure described by Pr2Rh3Ge crystallizes in the trigonal R-3m space group. Pr(1) is bonded in a 3-coordinate geometry to nine equivalent Rh(1) and three equivalent Ge(1) atoms. Rh(1) is bonded to six equivalent Pr(1), four equivalent Rh(1), and two equivalent Ge(1) atoms to form distorted RhPr6Ge2Rh4 cuboctahedra that share corners with four equivalent Ge(1)Pr6Rh6 cuboctahedra, corners with fourteen equivalent Rh(1)Pr6Ge2Rh4 cuboctahedra, edges with six equivalent Rh(1)Pr6Ge2Rh4 cuboctahedra, faces with six equivalent Ge(1)Pr6Rh6 cuboctahedra, and faces with twelve equivalent Rh(1)Pr6Ge2Rh4 cuboctahedra. Ge(1) is bonded to six equivalent Pr(1) and six equivalent Rh(1) atoms to form distorted GePr6Rh6 cuboctahedra that share corners with six equivalent Ge(1)Pr6Rh6 cuboctahedra, corners with twelve equivalent Rh(1)Pr6Ge2Rh4 cuboctahedra, edges with six equivalent Ge(1)Pr6Rh6 cuboctahedra, and faces with eighteen equivalent Rh(1)Pr6Ge2Rh4 cuboctahedra. is represented by the CIF card [CIF]
