Materials Data on KGdO2 by Materials Project
KGdO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. K1+ is bonded to six equivalent O2- atoms to form distorted KO6 octahedra that share corners with six equivalent GdO6 octahedra, edges with six equivalent KO6 octahedra, and edges with six equivalent GdO6 octahedra. The corner-sharing octahedral tilt angles are 14°. All K–O bond lengths are 2.83 Å. Gd3+ is bonded to six equivalent O2- atoms to form GdO6 octahedra that share corners with six equivalent KO6 octahedra, edges with six equivalent KO6 octahedra, and edges with six equivalent GdO6 octahedra. The corner-sharing octahedral tilt angles are 14°. All Gd–O bond lengths are 2.36 Å. O2- is bonded to three equivalent K1+ and three equivalent Gd3+ atoms to form a mixture of distorted edge and corner-sharing OK3Gd3 octahedra. The corner-sharing octahedral tilt angles are 0°.
