The material structure described by UF6 is alpha U structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four uranium hexafluoride molecules. U(1) is bonded in an octahedral geometry to one F(2), one F(4), two equivalent F(1), and two equivalent F(3) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one U(1) atom. In the second F site, F(2) is bonded in a single-bond geometry to one U(1) atom. In the third F site, F(3) is bonded in a single-bond geometry to one U(1) atom. In the fourth F site, F(4) is bonded in a single-bond geometry to one U(1) atom. is represented by the CIF card [CIF]
