Title: Materials Data on PuGa5Co by Materials Project

Abstract

PuCoGa5 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Pu is bonded to twelve Ga atoms to form PuGa12 cuboctahedra that share corners with four equivalent PuGa12 cuboctahedra, faces with four equivalent PuGa12 cuboctahedra, and faces with four equivalent GaPu4Ga8 cuboctahedra. There are eight shorter (2.94 Å) and four longer (2.98 Å) Pu–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 five inequivalent Ga sites. In the first Ga site, Ga is bonded in a 4-coordinate geometry to two equivalent Pu, two equivalent Co, and seven Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.62–2.98 Å. In the second Ga site, Ga is bonded in a 4-coordinate geometry to two equivalent Pu, two equivalent Co, and seven Ga atoms. There are two shorter (2.94 Å) and four longer (2.98 Å) Ga–Ga bond lengths. In the third Ga site, Ga is bonded in a 4-coordinate geometry to two equivalent Pu, two equivalent Co, and seven Ga atoms. There are one shorter (2.62 Å) and two longer (2.94 Å) Ga–Ga bond lengths. In the fourth Ga site, Ga is bondedmore » in a 4-coordinate geometry to two equivalent Pu, two equivalent Co, and seven Ga atoms. Both Ga–Ga bond lengths are 2.94 Å. In the fifth Ga site, Ga is bonded to four equivalent Pu and eight Ga atoms to form GaPu4Ga8 cuboctahedra that share corners with four equivalent GaPu4Ga8 cuboctahedra, faces with four equivalent PuGa12 cuboctahedra, and faces with four equivalent GaPu4Ga8 cuboctahedra.« less
