The material structure described by Sc11Ru4 crystallizes in the cubic Fm-3m space group. The structure consists of four Sc6Ru clusters inside a Sc16Ru7 framework. In each Sc6Ru cluster, Sc(1) is bonded in a single-bond geometry to one Ru(1) atom. Ru(1) is bonded in an octahedral geometry to six equivalent Sc(1) atoms. In the Sc16Ru7 framework, there are two inequivalent Sc sites. In the first Sc site, Sc(2) is bonded to one Ru(2) and three equivalent Ru(3) atoms to form a mixture of distorted corner and edge-sharing ScRu4 tetrahedra. In the second Sc site, Sc(3) is bonded in a distorted trigonal planar geometry to three equivalent Ru(3) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(2) is bonded in a body-centered cubic geometry to eight equivalent Sc(2) atoms. In the second Ru site, Ru(3) is bonded in a 8-coordinate geometry to four equivalent Sc(2) and four equivalent Sc(3) atoms. is represented by the CIF file [CIF]
