The crystal structure described by BiYbO3 is Ilmenite-like structured and crystallizes in the trigonal R3c space group. Yb(1) is bonded to six equivalent O(1) atoms to form distorted YbO6 pentagonal pyramids that share corners with three equivalent Bi(1)O6 octahedra, corners with six equivalent Yb(1)O6 pentagonal pyramids, edges with three equivalent Bi(1)O6 octahedra, and  a faceface with one Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles are 65°. Bi(1) is bonded to six equivalent O(1) atoms to form BiO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra, corners with three equivalent Yb(1)O6 pentagonal pyramids, edges with three equivalent Yb(1)O6 pentagonal pyramids, and  a faceface with one Yb(1)O6 pentagonal pyramid. The corner-sharing octahedral tilt angles are 42°. O(1) is bonded in a distorted see-saw-like geometry to two equivalent Yb(1) and two equivalent Bi(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
