Materials Data on RbLaNb2O7 by Materials Project
RbLaNb2O7 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Rb1+ is bonded in a distorted body-centered cubic geometry to eight equivalent O2- atoms. There are a spread of Rb–O bond distances ranging from 2.94–3.43 Å. La3+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of La–O bond distances ranging from 2.33–2.86 Å. Nb5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Nb–O bond distances ranging from 1.80–2.35 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent La3+ and two equivalent Nb5+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent La3+ and two equivalent Nb5+ atoms. In the third O2- site, O2- is bonded in a distorted single-bond geometry to four equivalent Rb1+ and one Nb5+ atom. In the fourth O2- site, O2- is bonded in a distorted linear geometry to two equivalent La3+ and two equivalent Nb5+ atoms.
