Materials Data on Sm4CdIr by Materials Project

Abstract

Sm4IrCd crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are three inequivalent Sm sites. In the first Sm site, Sm is bonded in a 3-coordinate geometry to three equivalent Ir and three equivalent Cd atoms. All Sm–Ir bond lengths are 2.89 Å. All Sm–Cd bond lengths are 3.52 Å. In the second Sm site, Sm is bonded in a distorted bent 150 degrees geometry to two equivalent Ir and two equivalent Cd atoms. Both Sm–Ir bond lengths are 2.86 Å. Both Sm–Cd bond lengths are 3.58 Å. In the third Sm site, Sm is bonded in a 4-coordinate geometry to two equivalent Ir and two equivalent Cd atoms. Both Sm–Ir bond lengths are 3.55 Å. Both Sm–Cd bond lengths are 3.34 Å. Ir is bonded in a 6-coordinate geometry to nine Sm atoms. Cd is bonded to nine Sm and three equivalent Cd atoms to form a mixture of distorted corner and face-sharing CdSm9Cd3 cuboctahedra. All Cd–Cd bond lengths are 3.17 Å.
