Materials Data on ErGa5Co by Materials Project
ErCoGa5 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Er is bonded to twelve Ga atoms to form ErGa12 cuboctahedra that share corners with four equivalent ErGa12 cuboctahedra, faces with four equivalent ErGa12 cuboctahedra, and faces with four equivalent GaEr4Ga8 cuboctahedra. All Er–Ga bond lengths are 2.98 Å. Co is bonded in a body-centered cubic geometry to eight equivalent Ga atoms. All Co–Ga bond lengths are 2.47 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 4-coordinate geometry to two equivalent Er, two equivalent Co, and seven Ga atoms. There are one shorter (2.59 Å) and six longer (2.98 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded to four equivalent Er and eight equivalent Ga atoms to form distorted GaEr4Ga8 cuboctahedra that share corners with four equivalent GaEr4Ga8 cuboctahedra, faces with four equivalent ErGa12 cuboctahedra, and faces with four equivalent GaEr4Ga8 cuboctahedra.
