Materials Data on RbCa2Nb3O10 by Materials Project
RbCa2Nb3O10 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Rb1+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Rb–O bond lengths are 3.20 Å. Ca2+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Ca–O bond distances ranging from 2.54–3.04 Å. There are two inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to six O2- atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Nb–O bond lengths are 1.98 Å. In the second Nb5+ site, Nb5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Nb–O bond distances ranging from 1.80–2.32 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to four equivalent Rb1+ and one Nb5+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ca2+ and two equivalent Nb5+ atoms. In the third O2- site, O2- is bonded in a linear geometry to four equivalent Ca2+ and two equivalent Nb5+ atoms. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to four equivalent Ca2+ and two Nb5+ atoms.
