Materials Data on DyGa5Co by Materials Project

Abstract

DyCoGa5 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Dy is bonded to twelve Ga atoms to form DyGa12 cuboctahedra that share corners with four equivalent DyGa12 cuboctahedra, faces with four equivalent DyGa12 cuboctahedra, and faces with four equivalent GaDy4Ga8 cuboctahedra. There are eight shorter (2.98 Å) and four longer (2.99 Å) Dy–Ga bond lengths. Co is bonded in a body-centered cubic geometry to eight Ga atoms. All Co–Ga bond lengths are 2.48 Å. There are four inequivalent Ga sites. In the first 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, faces with four equivalent DyGa12 cuboctahedra, and faces with four equivalent GaDy4Ga8 cuboctahedra. All Ga–Ga bond lengths are 2.98 Å. In the second Ga site, Ga is bonded in a 4-coordinate geometry to two equivalent Dy, two equivalent Co, and seven Ga atoms. There are one shorter (2.58 Å) and four longer (2.99 Å) Ga–Ga bond lengths. In the third Ga site, Ga is bonded in a 4-coordinate geometry to two equivalent Dy, two equivalent Co, and seven Ga atoms. The Ga–Ga bond length is 2.58 Å. In the fourth Ga site, Ga is bonded in a 4-coordinate geometry to two equivalent Dy, two equivalent Co, and seven Ga atoms. All Ga–Ga bond lengths are 2.99 Å.
