Materials Data on RbAlO2 by Materials Project
RbAlO2 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Rb1+ is bonded in a 12-coordinate geometry to twelve equivalent O2- atoms. All Rb–O bond lengths are 3.36 Å. Al3+ is bonded to four equivalent O2- atoms to form corner-sharing AlO4 tetrahedra. All Al–O bond lengths are 1.76 Å. O2- is bonded in a linear geometry to six equivalent Rb1+ and two equivalent Al3+ atoms.
