Materials Data on RbDyO2 by Materials Project

RbDyO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Rb1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Rb–O bond lengths are 2.94 Å. Dy3+ is bonded to six equivalent O2- atoms to form edge-sharing DyO6 octahedra. All Dy–O bond lengths are 2.33 Å. O2- is bonded to three equivalent Rb1+ and three equivalent Dy3+ atoms to form a mixture of distorted edge and corner-sharing ORb3Dy3 octahedra. The corner-sharing octahedral tilt angles are 0°.

Materials Data on RbDyO3 by Materials Project

RbDyO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rb is bonded to twelve equivalent O atoms to form RbO12 cuboctahedra that share corners with twelve equivalent RbO12 cuboctahedra, faces with six equivalent RbO12 cuboctahedra, and faces with eight equivalent DyO6 octahedra. All Rb–O bond lengths are 3.20 Å. Dy is bonded to six equivalent O atoms to form DyO6 octahedra that share corners with six equivalent DyO6 octahedra and faces with eight equivalent RbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Dy–O bond lengths are 2.26 Å. O is bonded in a distorted linear geometry to four equivalent Rb and two equivalent Dy atoms.
