Materials Data on Rb3LuO3 by Materials Project
Rb3LuO3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Rb–O bond distances ranging from 2.89–3.50 Å. In the second Rb1+ site, Rb1+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. There are two shorter (2.95 Å) and two longer (3.15 Å) Rb–O bond lengths. In the third Rb1+ site, Rb1+ is bonded in a 1-coordinate geometry to five O2- atoms. There are a spread of Rb–O bond distances ranging from 2.72–3.18 Å. Lu3+ is bonded to four O2- atoms to form edge-sharing LuO4 tetrahedra. There are a spread of Lu–O bond distances ranging from 2.07–2.15 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 7-coordinate geometry to six Rb1+ and one Lu3+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to three Rb1+ and two equivalent Lu3+ atoms.
