Materials Data on RbPaF6 by Materials Project

Abstract

RbPaF6 crystallizes in the orthorhombic Cmme space group. The structure is two-dimensional and consists of two RbPaF6 sheets oriented in the (0, 1, 0) direction. Rb1+ is bonded in a distorted body-centered cubic geometry to eight equivalent F1- atoms. There are four shorter (3.01 Å) and four longer (3.08 Å) Rb–F bond lengths. Pa5+ is bonded in a body-centered cubic geometry to eight F1- atoms. There are four shorter (2.13 Å) and four longer (2.34 Å) Pa–F bond lengths. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one Pa5+ atom. In the second F1- site, F1- is bonded in a bent 120 degrees geometry to two equivalent Pa5+ atoms.
