Title: Materials Data on UGa5Fe by Materials Project

Abstract

UFeGa5 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. U is bonded to twelve Ga atoms to form UGa12 cuboctahedra that share corners with four equivalent UGa12 cuboctahedra, faces with four equivalent UGa12 cuboctahedra, and faces with four equivalent GaU4Ga8 cuboctahedra. There are eight shorter (2.97 Å) and four longer (3.03 Å) U–Ga bond lengths. Fe is bonded in a body-centered cubic geometry to eight Ga atoms. All Fe–Ga bond lengths are 2.50 Å. There are four inequivalent Ga sites. In the first Ga site, Ga is bonded to four equivalent U and eight Ga atoms to form GaU4Ga8 cuboctahedra that share corners with four equivalent GaU4Ga8 cuboctahedra, faces with four equivalent UGa12 cuboctahedra, and faces with four equivalent GaU4Ga8 cuboctahedra. All Ga–Ga bond lengths are 2.97 Å. In the second Ga site, Ga is bonded in a 11-coordinate geometry to two equivalent U, two equivalent Fe, and seven Ga atoms. There are one shorter (2.57 Å) and four longer (3.03 Å) Ga–Ga bond lengths. In the third Ga site, Ga is bonded in a 11-coordinate geometry to two equivalent U, two equivalent Fe, and seven Ga atoms.
