Ba2YbBiO6 crystallizes in the trigonal R-3 space group. Ba(1) is bonded to twelve equivalent O(1) atoms to form distorted BaO12 cuboctahedra that share corners with twelve equivalent Ba(1)O12 cuboctahedra, faces with six equivalent Ba(1)O12 cuboctahedra, faces with four equivalent Yb(1)O6 octahedra, and faces with four equivalent Bi(1)O6 octahedra. Yb(1) is bonded to six equivalent O(1) atoms to form YbO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 11°. Bi(1) is bonded to six equivalent O(1) atoms to form BiO6 octahedra that share corners with six equivalent Yb(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 11°. O(1) is bonded in a 2-coordinate geometry to four equivalent Ba(1), one Yb(1), and one Bi(1) atom.
