The structure described by Zr11Os4 crystallizes in the cubic Fm-3m space group. The structure consists of four Zr6Os clusters inside a Zr16Os7 framework. In each Zr6Os cluster, Zr(1) is bonded in a single-bond geometry to one Os(1) atom. Os(1) is bonded in an octahedral geometry to six equivalent Zr(1) atoms. In the Zr16Os7 framework, there are two inequivalent Zr sites. In the first Zr site, Zr(2) is bonded to one Os(2) and three equivalent Os(3) atoms to form a mixture of distorted corner and edge-sharing ZrOs4 tetrahedra. In the second Zr site, Zr(3) is bonded in a trigonal planar geometry to three equivalent Os(3) atoms. There are two inequivalent Os sites. In the first Os site, Os(2) is bonded in a body-centered cubic geometry to eight equivalent Zr(2) atoms. In the second Os site, Os(3) is bonded in a 8-coordinate geometry to four equivalent Zr(2) and four equivalent Zr(3) atoms. is represented by the CIF file [CIF]
