BiYO3 is Ilmenite-like structured and crystallizes in the trigonal R3c space group. Y(1) is bonded to six equivalent O(1) atoms to form distorted YO6 octahedra that share corners with three equivalent Bi(1)O6 octahedra, corners with six equivalent Y(1)O6 octahedra, edges with three equivalent Bi(1)O6 octahedra, and  a faceface with one Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-69°. Bi(1) is bonded to six equivalent O(1) atoms to form distorted BiO6 octahedra that share corners with three equivalent Y(1)O6 octahedra, corners with six equivalent Bi(1)O6 octahedra, edges with three equivalent Y(1)O6 octahedra, and  a faceface with one Y(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 54-69°. O(1) is bonded in a distorted see-saw-like geometry to two equivalent Y(1) and two equivalent Bi(1) atoms.
