Materials Data on Yb3Ga8Rh3 by Materials Project

Abstract

Yb3Rh3Ga8 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are two inequivalent Yb sites. In the first Yb site, Yb is bonded in a 12-coordinate geometry to four equivalent Rh and twelve Ga atoms. All Yb–Rh bond lengths are 3.48 Å. There are four shorter (3.22 Å) and eight longer (3.28 Å) Yb–Ga bond lengths. In the second Yb site, Yb is bonded in a 12-coordinate geometry to four Rh and eight Ga atoms. All Yb–Rh bond lengths are 3.06 Å. There are four shorter (3.03 Å) and four longer (3.21 Å) Yb–Ga bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 8-coordinate geometry to four equivalent Yb and four equivalent Ga atoms. All Rh–Ga bond lengths are 2.55 Å. In the second Rh site, Rh is bonded in a 12-coordinate geometry to four Yb and six Ga atoms. There are two shorter (2.54 Å) and four longer (2.62 Å) Rh–Ga bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 9-coordinate geometry to three Yb, three Rh, and three equivalent Ga atoms. There are two shorter (2.66 Å) and one longer (2.76 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded in a 1-coordinate geometry to four Yb, one Rh, and three equivalent Ga atoms.
