Materials Data on RbMoPO6 by Materials Project
RbMoPO6 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 2.96–3.44 Å. Mo6+ is bonded to six O2- atoms to form distorted MoO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are a spread of Mo–O bond distances ranging from 1.73–2.24 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent MoO6 octahedra. The corner-sharing octahedra tilt angles range from 37–44°. There is two shorter (1.53 Å) and two longer (1.57 Å) P–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Mo6+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Rb1+, one Mo6+, and one P5+ atom.
