Materials Data on Eu2(Ga3Rh)3 by Materials Project

Abstract

Eu2(RhGa3)3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Eu is bonded in a 11-coordinate geometry to eleven Ga atoms. There are a spread of Eu–Ga bond distances ranging from 3.11–3.18 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 8-coordinate geometry to eight Ga atoms. There are a spread of Rh–Ga bond distances ranging from 2.62–2.65 Å. In the second Rh site, Rh is bonded in a 8-coordinate geometry to eight Ga atoms. There are a spread of Rh–Ga bond distances ranging from 2.64–2.66 Å. There are four inequivalent Ga sites. In the first Ga site, Ga is bonded in a 3-coordinate geometry to three equivalent Eu, three Rh, and five Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.80–3.00 Å. In the second Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Eu, two equivalent Rh, and six Ga atoms. Both Ga–Ga bond lengths are 2.76 Å. In the third Ga site, Ga is bonded in a 3-coordinate geometry to two equivalent Eu, three Rh, and five Ga atoms. There are one shorter (2.76 Å) and two longer (2.91 Å) Ga–Ga bond lengths. In the fourth Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Eu, two equivalent Rh, and six Ga atoms. The Ga–Ga bond length is 2.75 Å.
