Materials Data on RbB2SbO6 by Materials Project
RbB2SbO6 crystallizes in the orthorhombic Pmn2_1 space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 3.01–3.26 Å. B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.35–1.41 Å. Sb5+ is bonded to six O2- atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles are 2°. There are a spread of Sb–O bond distances ranging from 1.94–2.01 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one B3+, and one Sb5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Rb1+ and two equivalent B3+ atoms. In the third O2- site, O2- is bonded in a linear geometry to two equivalent Sb5+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one B3+, and one Sb5+ atom.
