Title: Materials Data on Yb(GaFe)6 by Materials Project

Abstract

Yb(FeGa)6 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Yb is bonded to twelve Fe and eight Ga atoms to form distorted YbGa8Fe12 hexagonal bipyramids that share corners with eight equivalent YbGa8Fe12 hexagonal bipyramids, faces with twenty-four FeYb2Ga6Fe4 cuboctahedra, and faces with two equivalent YbGa8Fe12 hexagonal bipyramids. There are four shorter (3.27 Å) and eight longer (3.28 Å) Yb–Fe bond lengths. There are a spread of Yb–Ga bond distances ranging from 2.79–2.95 Å. There are two inequivalent Fe sites. In the first Fe site, Fe is bonded to two equivalent Yb, four equivalent Fe, and six Ga atoms to form distorted FeYb2Ga6Fe4 cuboctahedra that share corners with fourteen FeYb2Ga6Fe4 cuboctahedra, edges with seven FeYb2Ga6Fe4 cuboctahedra, faces with nine FeYb2Ga6Fe4 cuboctahedra, and faces with four equivalent YbGa8Fe12 hexagonal bipyramids. All Fe–Fe bond lengths are 2.50 Å. There are a spread of Fe–Ga bond distances ranging from 2.56–2.61 Å. In the second Fe site, Fe is bonded to two equivalent Yb, four Fe, and six Ga atoms to form distorted FeYb2Ga6Fe4 cuboctahedra that share corners with fourteen FeYb2Ga6Fe4 cuboctahedra, edges with six FeYb2Ga6Fe4 cuboctahedra, faces with ten FeYb2Ga6Fe4 cuboctahedra, and faces with four equivalent YbGa8Fe12 hexagonal bipyramids. Both Fe–Femore » bond lengths are 2.51 Å. There are two shorter (2.54 Å) and four longer (2.59 Å) Fe–Ga bond lengths. There are five inequivalent Ga sites. In the first Ga site, Ga is bonded in a 1-coordinate geometry to one Yb, six Fe, and one Ga atom. The Ga–Yb bond length is 2.79 Å. There are four shorter (2.59 Å) and two longer (2.61 Å) Ga–Fe bond lengths. The Ga–Ga bond length is 2.91 Å. In the second Ga site, Ga is bonded in a 1-coordinate geometry to one Yb, six Fe, and one Ga atom. The Ga–Yb bond length is 2.79 Å. In the third Ga site, Ga is bonded in a 10-coordinate geometry to one Yb, six Fe, and three Ga atoms. There are one shorter (2.76 Å) and two longer (2.87 Å) Ga–Ga bond lengths. In the fourth Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Yb, six Fe, and two equivalent Ga atoms. In the fifth Ga site, Ga is bonded in a 1-coordinate geometry to one Yb, six Fe, and one Ga atom. Both Ga–Fe bond lengths are 2.61 Å. The Ga–Ga bond length is 2.91 Å.« less
