Materials Data on RbNa3Mo2H18O17 by Materials Project
RbNa3Mo2H18O17 crystallizes in the hexagonal P6_3/m space group. The structure is two-dimensional and consists of two RbNa3Mo2H18O17 sheets oriented in the (0, 0, 1) direction. Rb1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Rb–O bond lengths are 3.03 Å. Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with two equivalent MoO4 tetrahedra and faces with two equivalent NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.34–2.49 Å. Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with three equivalent NaO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There is one shorter (1.78 Å) and three longer (1.81 Å) Mo–O bond length. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to two equivalent Na1+ and two equivalent H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Rb1+, one Na1+, and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent Na1+ and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one Mo6+ atom.
