Materials Data on USb2F15 by Materials Project
(USbF10)2(SbF4)2F2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two fluorine molecules, four SbF4 clusters, and two USbF10 clusters. In each SbF4 cluster, Sb5+ is bonded in a distorted trigonal pyramidal geometry to four F1- atoms. There are a spread of Sb–F bond distances ranging from 1.90–1.97 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In each USbF10 cluster, U5+ is bonded to six F1- atoms to form UF6 octahedra that share corners with two equivalent SbF6 octahedra. The corner-sharing octahedra tilt angles range from 22–24°. There are a spread of U–F bond distances ranging from 1.99–2.32 Å. Sb5+ is bonded to six F1- atoms to form SbF6 octahedra that share corners with two equivalent UF6 octahedra. The corner-sharing octahedra tilt angles range from 22–24°. There are a spread of Sb–F bond distances ranging from 1.88–2.05 Å. There are ten inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one U5+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one U5+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the sixth F1- site, F1- is bonded in a bent 150 degrees geometry to one U5+ and one Sb5+ atom. In the seventh F1- site, F1- is bonded in a single-bond geometry to one U5+ atom. In the eighth F1- site, F1- is bonded in a bent 150 degrees geometry to one U5+ and one Sb5+ atom. In the ninth F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the tenth F1- site, F1- is bonded in a single-bond geometry to one U5+ atom.
