Abstract

Dy4CrGa12 crystallizes in the cubic Im-3m space group. The structure is three-dimensional. Dy is bonded to twelve Ga atoms to form DyGa12 cuboctahedra that share corners with twelve equivalent DyGa12 cuboctahedra, edges with twelve equivalent GaDy4Ga8 cuboctahedra, faces with six equivalent DyGa12 cuboctahedra, faces with six equivalent GaDy4Ga8 cuboctahedra, and faces with two equivalent CrGa6 octahedra. There are six shorter (3.05 Å) and six longer (3.06 Å) Dy–Ga bond lengths. Cr is bonded to six equivalent Ga atoms to form CrGa6 octahedra that share corners with twenty-four equivalent GaDy4Ga8 cuboctahedra and faces with eight equivalent DyGa12 cuboctahedra. All Cr–Ga bond lengths are 2.46 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 5-coordinate geometry to four equivalent Dy, one Cr, and four equivalent Ga atoms. All Ga–Ga bond lengths are 2.84 Å. In the second Ga site, Ga is bonded to four equivalent Dy and eight Ga atoms to form distorted GaDy4Ga8 cuboctahedra that share corners with four equivalent GaDy4Ga8 cuboctahedra, corners with four equivalent CrGa6 octahedra, edges with eight equivalent DyGa12 cuboctahedra, edges with eight equivalent GaDy4Ga8 cuboctahedra, faces with four equivalent DyGa12 cuboctahedra, and faces with six equivalent GaDy4Ga8 cuboctahedra.more »« less
