Abstract

Sm23Rh7Cd4 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are nine inequivalent Sm sites. In the first Sm site, Sm is bonded in a distorted bent 150 degrees geometry to two equivalent Rh and two Cd atoms. Both Sm–Rh bond lengths are 2.86 Å. Both Sm–Cd bond lengths are 3.62 Å. In the second Sm site, Sm is bonded in a distorted T-shaped geometry to three Rh atoms. There are two shorter (2.92 Å) and one longer (3.00 Å) Sm–Rh bond lengths. In the third Sm site, Sm is bonded in a distorted bent 150 degrees geometry to two Rh and two equivalent Cd atoms. There are one shorter (2.83 Å) and one longer (2.86 Å) Sm–Rh bond lengths. Both Sm–Cd bond lengths are 3.60 Å. In the fourth Sm site, Sm is bonded in a 3-coordinate geometry to three Rh and three Cd atoms. There are one shorter (2.88 Å) and two longer (2.89 Å) Sm–Rh bond lengths. There are two shorter (3.49 Å) and one longer (3.52 Å) Sm–Cd bond lengths. In the fifth Sm site, Sm is bonded in a 3-coordinate geometry to two equivalent Rh and one Cd atom. Both Sm–Rh bondmore »« less
