Materials Data on Yb3Ga8Ir3 by Materials Project
Yb3Ir3Ga8 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 Ir and twelve Ga atoms. All Yb–Ir bond lengths are 3.44 Å. There are four shorter (3.20 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 Ir and eight Ga atoms. There are two shorter (3.05 Å) and two longer (3.07 Å) Yb–Ir bond lengths. There are four shorter (3.02 Å) and four longer (3.19 Å) Yb–Ga bond lengths. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 8-coordinate geometry to four equivalent Yb and four equivalent Ga atoms. All Ir–Ga bond lengths are 2.56 Å. In the second Ir site, Ir 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) Ir–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 Ir, and three equivalent Ga atoms. There are two shorter (2.66 Å) and one longer (2.74 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded in a 1-coordinate geometry to four Yb, one Ir, and three equivalent Ga atoms.
