Abstract

Sc3(FeGa3)2 is Bergman Structure: Mg32(Al,Zn)49 Bergman-like structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Sc sites. In the first Sc site, Sc is bonded in a 12-coordinate geometry to three Fe and nine Ga atoms. There are a spread of Sc–Fe bond distances ranging from 2.91–3.13 Å. There are a spread of Sc–Ga bond distances ranging from 2.84–3.10 Å. In the second Sc site, Sc is bonded in a 1-coordinate geometry to two Fe and eleven Ga atoms. There are one shorter (3.05 Å) and one longer (3.23 Å) Sc–Fe bond lengths. There are a spread of Sc–Ga bond distances ranging from 2.73–3.36 Å. There are two inequivalent Fe sites. In the first Fe site, Fe is bonded to five Sc, one Fe, and six Ga atoms to form FeSc5Ga6Fe cuboctahedra that share corners with five equivalent FeSc3Ga8Fe cuboctahedra, edges with two equivalent FeSc5Ga6Fe cuboctahedra, and faces with two equivalent FeSc3Ga8Fe cuboctahedra. The Fe–Fe bond length is 2.55 Å. There are a spread of Fe–Ga bond distances ranging from 2.40–2.61 Å. In the second Fe site, Fe is bonded to three Sc, one Fe, and eight Ga atoms to form amore »« less
