Abstract

YFe6Ga6 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Y is bonded to twelve Fe and eight Ga atoms to form distorted YGa8Fe12 hexagonal bipyramids that share corners with eight equivalent YGa8Fe12 hexagonal bipyramids, faces with twenty-four FeY2Ga6Fe4 cuboctahedra, and faces with two equivalent YGa8Fe12 hexagonal bipyramids. There are four shorter (3.28 Å) and eight longer (3.30 Å) Y–Fe bond lengths. There are a spread of Y–Ga bond distances ranging from 2.85–2.99 Å. There are two inequivalent Fe sites. In the first Fe site, Fe is bonded to two equivalent Y, four equivalent Fe, and six Ga atoms to form distorted FeY2Ga6Fe4 cuboctahedra that share corners with fourteen FeY2Ga6Fe4 cuboctahedra, edges with seven FeY2Ga6Fe4 cuboctahedra, faces with nine FeY2Ga6Fe4 cuboctahedra, and faces with four equivalent YGa8Fe12 hexagonal bipyramids. All Fe–Fe bond lengths are 2.51 Å. There are a spread of Fe–Ga bond distances ranging from 2.57–2.64 Å. In the second Fe site, Fe is bonded to two equivalent Y, four Fe, and six Ga atoms to form distorted FeY2Ga6Fe4 cuboctahedra that share corners with fourteen FeY2Ga6Fe4 cuboctahedra, edges with six FeY2Ga6Fe4 cuboctahedra, faces with ten FeY2Ga6Fe4 cuboctahedra, and faces with four equivalent YGa8Fe12 hexagonal bipyramids.
