Pr7Rh3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Rh(1) atoms. In the second Pr site, Pr(3) is bonded in a distorted water-like geometry to two equivalent Rh(1) atoms. In the third Pr site, Pr(2) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. Rh(1) is bonded in a 6-coordinate geometry to one Pr(1), two equivalent Pr(3), and three equivalent Pr(2) atoms.
Pr7Rh3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Rh(1) atoms. All Pr(1)-Rh(1) bond lengths are 2.93 Å. In the second Pr site, Pr(3) is bonded in a distorted water-like geometry to two equivalent Rh(1) atoms. Both Pr(3)-Rh(1) bond lengths are 2.92 Å. In the third Pr site, Pr(2) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. There is one shorter (2.98 Å) and two longer (2.99 Å) Pr(2)-Rh(1) bond lengths. Rh(1) is bonded in a 6-coordinate geometry to one Pr(1), two equivalent Pr(3), and three equivalent Pr(2) atoms.
