Yb(Rh3P2)2 crystallizes in the hexagonal P-6 space group. Yb(1) is bonded to six equivalent Rh(2) and six equivalent P(2) atoms to form distorted face-sharing YbP6Rh6 cuboctahedra. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to one P(1) and four equivalent P(2) atoms. In the second Rh site, Rh(2) is bonded in a 6-coordinate geometry to two equivalent Yb(1), two equivalent P(1), and two equivalent P(2) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 9-coordinate geometry to three equivalent Rh(1) and six equivalent Rh(2) atoms. In the second P site, P(2) is bonded in a 8-coordinate geometry to two equivalent Yb(1), two equivalent Rh(2), and four equivalent Rh(1) atoms.
Yb(Rh3P2)2 crystallizes in the hexagonal P-6 space group. Yb(1) is bonded to six equivalent Rh(2) and six equivalent P(2) atoms to form distorted face-sharing YbP6Rh6 cuboctahedra. All Yb(1)-Rh(2) bond lengths are 3.04 Å. All Yb(1)-P(2) bond lengths are 2.94 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to one P(1) and four equivalent P(2) atoms. The Rh(1)-P(1) bond length is 2.44 Å. There are two shorter (2.44 Å) and two longer (2.60 Å) Rh(1)-P(2) bond lengths. In the second Rh site, Rh(2) is bonded in a 6-coordinate geometry to two equivalent Yb(1), two equivalent P(1), and two equivalent P(2) atoms. Both Rh(2)-P(1) bond lengths are 2.48 Å. There is one shorter (2.33 Å) and one longer (2.37 Å) Rh(2)-P(2) bond length. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 9-coordinate geometry to three equivalent Rh(1) and six equivalent Rh(2) atoms. In the second P site, P(2) is bonded in a 8-coordinate geometry to two equivalent Yb(1), two equivalent Rh(2), and four equivalent Rh(1) atoms.
