Materials Data on Rb3RuF12 by Materials Project
Rb3RuF12 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Rb sites. In the first Rb site, Rb is bonded to eight F atoms to form distorted edge-sharing RbF8 hexagonal bipyramids. There are four shorter (2.96 Å) and four longer (3.01 Å) Rb–F bond lengths. In the second Rb site, Rb is bonded to six F atoms to form edge-sharing RbF6 octahedra. There are a spread of Rb–F bond distances ranging from 2.73–2.93 Å. Ru is bonded in a square co-planar geometry to four equivalent F atoms. All Ru–F bond lengths are 1.90 Å. There are three inequivalent F sites. In the first F site, F is bonded in a 2-coordinate geometry to two Rb and one F atom. The F–F bond length is 1.82 Å. In the second F site, F is bonded in a 2-coordinate geometry to two Rb and one F atom. In the third F site, F is bonded in a distorted single-bond geometry to one Rb and one Ru atom.
