Materials Data on Gd2(Ga3Ir)3 by Materials Project

Abstract

Gd2(IrGa3)3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Gd is bonded in a 11-coordinate geometry to eleven Ga atoms. There are a spread of Gd–Ga bond distances ranging from 3.04–3.15 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 2.59–2.65 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 2.57–2.64 Å. There are four inequivalent Ga sites. In the first Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Gd, two equivalent Ir, and six Ga atoms. All Ga–Ga bond lengths are 2.77 Å. In the second Ga site, Ga is bonded in a 3-coordinate geometry to three equivalent Gd, three Ir, and five Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.79–2.94 Å. In the third Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Gd, three Ir, and five Ga atoms. There are one shorter (2.78 Å) and two longer (2.85 Å) Ga–Ga bond lengths. In the fourth Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Gd, two equivalent Ir, and six Ga atoms. The Ga–Ga bond length is 2.75 Å.
