Materials Data on Rb2RuO4 by Materials Project

Rb2RuO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 1-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 2.81–3.52 Å. In the second Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.92–3.51 Å. Ru6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Ru–O bond distances ranging from 1.79–1.81 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to five Rb1+ and one Ru6+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to four Rb1+ and one Ru6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to five Rb1+ and one Ru6+ atom.

Materials Data on RbRuO3 by Materials Project

RbRuO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rb1+ is bonded to twelve equivalent O2- atoms to form RbO12 cuboctahedra that share corners with twelve equivalent RbO12 cuboctahedra, faces with six equivalent RbO12 cuboctahedra, and faces with eight equivalent RuO6 octahedra. All Rb–O bond lengths are 2.81 Å. Ru5+ is bonded to six equivalent O2- atoms to form RuO6 octahedra that share corners with six equivalent RuO6 octahedra and faces with eight equivalent RbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ru–O bond lengths are 1.99 Å. O2- is bonded to four equivalent Rb1+ and two equivalent Ru5+ atoms to form a mixture of distorted face, edge, and corner-sharing ORb4Ru2 octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
