The compound described by U4Os is Iron carbide-like structured and crystallizes in the cubic Fd-3m space group. The structure is zero-dimensional and consists of eight U4Os clusters. U(1) is bonded in a single-bond geometry to one Os(1) atom. Os(1) is bonded in a tetrahedral geometry to four equivalent U(1) atoms. is represented by the CIF card [CIF]
