The material described by U2Zn17 is Indium-derived structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of twelve 7440-66-6 atoms, two U2Zn5 clusters, and four zinc molecules. In each U2Zn5 cluster, U(1) is bonded in a bent 150 degrees geometry to one Zn(3) and one Zn(6) atom. There are three inequivalent Zn sites. In the first Zn site, Zn(3) is bonded in a linear geometry to two equivalent U(1) atoms. In the second Zn site, Zn(1) is bonded in a single-bond geometry to one Zn(6) atom. In the third Zn site, Zn(6) is bonded in a distorted bent 120 degrees geometry to one U(1) and one Zn(1) atom. is represented by the CIF file [CIF]
