Sc16Os7Sc6Os crystallizes in the cubic Fm-3m space group. The structure consists of four Sc6Os clusters inside a Sc16Os7 framework. In each Sc6Os cluster, Sc(2) is bonded in a single-bond geometry to one Os(3) atom. Os(3) is bonded in an octahedral geometry to six equivalent Sc(2) atoms. In the Sc16Os7 framework, there are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a distorted trigonal planar geometry to three equivalent Os(1) atoms. In the second Sc site, Sc(3) is bonded to one Os(2) and three equivalent Os(1) atoms to form a mixture of distorted corner and edge-sharing ScOs4 tetrahedra. There are two inequivalent Os sites. In the first Os site, Os(2) is bonded in a body-centered cubic geometry to eight equivalent Sc(3) atoms. In the second Os site, Os(1) is bonded in a 8-coordinate geometry to four equivalent Sc(1) and four equivalent Sc(3) atoms.
