U4Os7Ge6 crystallizes in the cubic Im-3m space group. U(1) is bonded to six equivalent Os(1) and six equivalent Ge(1) atoms to form UGe6Os6 cuboctahedra that share corners with twelve equivalent U(1)Ge6Os6 cuboctahedra, faces with six equivalent U(1)Ge6Os6 cuboctahedra, and faces with two equivalent Os(2)Ge6 octahedra. There are two inequivalent Os sites. In the first Os site, Os(2) is bonded to six equivalent Ge(1) atoms to form OsGe6 octahedra that share faces with eight equivalent U(1)Ge6Os6 cuboctahedra. In the second Os site, Os(1) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent U(1), one Os(2), and four equivalent Os(1) atoms.
