Materials Data on Sm3(SiIr)2 by Materials Project
Sm3Ir2Si2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 2-coordinate geometry to five Ir and four equivalent Si atoms. There are a spread of Sm–Ir bond distances ranging from 3.00–3.47 Å. There are three shorter (3.07 Å) and one longer (3.13 Å) Sm–Si bond lengths. In the second Sm site, Sm is bonded in a 9-coordinate geometry to five Ir and four equivalent Si atoms. There are a spread of Sm–Ir bond distances ranging from 2.99–3.36 Å. All Sm–Si bond lengths are 3.11 Å. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 9-coordinate geometry to seven Sm and two equivalent Si atoms. Both Ir–Si bond lengths are 2.54 Å. In the second Ir site, Ir is bonded to eight Sm and four equivalent Si atoms to form a mixture of distorted corner, edge, and face-sharing IrSm8Si4 cuboctahedra. All Ir–Si bond lengths are 2.47 Å. Si is bonded in a 3-coordinate geometry to six Sm, three Ir, and one Si atom. The Si–Si bond length is 2.71 Å.
