Materials Data on RbTm3O6 by Materials Project
TmRbTm2O4O2 crystallizes in the orthorhombic Cmmm space group. The structure is two-dimensional and consists of two thulium molecules; four water molecules; and one RbTm2O4 sheet oriented in the (0, 0, 1) direction. In the RbTm2O4 sheet, Rb is bonded in a square co-planar geometry to four equivalent O atoms. All Rb–O bond lengths are 2.81 Å. Tm is bonded in a linear geometry to two equivalent O atoms. Both Tm–O bond lengths are 1.95 Å. O is bonded in a linear geometry to one Rb and one Tm atom.
