Materials Data on RbEr3O6 by Materials Project
ErRbEr2O4O2 crystallizes in the orthorhombic Cmmm space group. The structure is two-dimensional and consists of two erbium molecules; four water molecules; and one RbEr2O4 sheet oriented in the (0, 0, 1) direction. In the RbEr2O4 sheet, Rb is bonded in a square co-planar geometry to four equivalent O atoms. All Rb–O bond lengths are 2.82 Å. Er is bonded in a linear geometry to two equivalent O atoms. Both Er–O bond lengths are 1.96 Å. O is bonded in a linear geometry to one Rb and one Er atom.
