The crystal structure described by Pr(Rh3Ge2)2 crystallizes in the hexagonal P-6m2 space group. Pr(1) is bonded to six equivalent Rh(2) and six equivalent Ge(2) atoms to form face-sharing PrGe6Rh6 cuboctahedra. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to one Ge(1) and four equivalent Ge(2) atoms. In the second Rh site, Rh(2) is bonded in a 6-coordinate geometry to two equivalent Pr(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Rh(1) and six equivalent Rh(2) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to two equivalent Pr(1), two equivalent Rh(2), and four equivalent Rh(1) atoms. is represented by the CIF file [CIF]
