Abstract

ErFe6Ga6 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Er is bonded to twelve Fe and eight Ga atoms to form distorted ErGa8Fe12 hexagonal bipyramids that share corners with eight equivalent ErGa8Fe12 hexagonal bipyramids, faces with twenty-four FeEr2Ga6Fe4 cuboctahedra, and faces with two equivalent ErGa8Fe12 hexagonal bipyramids. There are four shorter (3.26 Å) and eight longer (3.28 Å) Er–Fe bond lengths. There are a spread of Er–Ga bond distances ranging from 2.83–2.97 Å. There are two inequivalent Fe sites. In the first Fe site, Fe is bonded to two equivalent Er, four equivalent Fe, and six Ga atoms to form distorted FeEr2Ga6Fe4 cuboctahedra that share corners with fourteen FeEr2Ga6Fe4 cuboctahedra, edges with seven FeEr2Ga6Fe4 cuboctahedra, faces with nine FeEr2Ga6Fe4 cuboctahedra, and faces with four equivalent ErGa8Fe12 hexagonal bipyramids. All Fe–Fe bond lengths are 2.50 Å. There are a spread of Fe–Ga bond distances ranging from 2.56–2.63 Å. In the second Fe site, Fe is bonded to two equivalent Er, four Fe, and six Ga atoms to form distorted FeEr2Ga6Fe4 cuboctahedra that share corners with fourteen FeEr2Ga6Fe4 cuboctahedra, edges with six FeEr2Ga6Fe4 cuboctahedra, faces with ten FeEr2Ga6Fe4 cuboctahedra, and faces with four equivalent ErGa8Fe12 hexagonal bipyramids.
