Title: Materials Data on Sm2(Ga3Ir)3 by Materials Project

Abstract

Sm2(IrGa3)3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Sm is bonded in a 11-coordinate geometry to eleven Ga atoms. There are a spread of Sm–Ga bond distances ranging from 3.04–3.18 Å. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 8-coordinate geometry to eight Ga atoms. There are a spread of Ir–Ga bond distances ranging from 2.60–2.66 Å. In the second Ir site, Ir is bonded in a 8-coordinate geometry to eight Ga atoms. There are a spread of Ir–Ga bond distances ranging from 2.59–2.65 Å. There are four inequivalent Ga sites. In the first Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Sm, two equivalent Ir, and six Ga atoms. There are two shorter (2.75 Å) and four longer (2.76 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded in a 3-coordinate geometry to three equivalent Sm, three Ir, and five Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.79–2.96 Å. In the third Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Sm, three Ir, and five Ga atoms. There are one shortermore » (2.80 Å) and two longer (2.84 Å) Ga–Ga bond lengths. In the fourth Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Sm, two equivalent Ir, and six Ga atoms. The Ga–Ga bond length is 2.72 Å.« less
