Materials Data on UGa5Ir by Materials Project
UIrGa5 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. U is bonded to twelve Ga atoms to form distorted 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 (2.96 Å) and four longer (3.07 Å) U–Ga bond lengths. Ir is bonded in a body-centered cubic geometry to eight equivalent Ga atoms. All Ir–Ga bond lengths are 2.57 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 4-coordinate geometry to two equivalent U, two equivalent Ir, and two equivalent Ga atoms. Both Ga–Ga bond lengths are 2.96 Å. In the second Ga site, Ga is bonded to four equivalent U and eight equivalent 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.
