Bi4(PO4)3 crystallizes in the cubic I-43d space group. Bi(1) is bonded to six equivalent O(1) atoms to form distorted BiO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra and edges with three equivalent Bi(1)O6 octahedra. P(1) is bonded to four equivalent O(1) atoms to form PO4 tetrahedra that share corners with eight equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-68°. O(1) is bonded in a distorted single-bond geometry to two equivalent Bi(1) and one P(1) atom.
Bi4(PO4)3 crystallizes in the cubic I-43d space group. Bi(1) is bonded to six equivalent O(1) atoms to form distorted BiO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra and edges with three equivalent Bi(1)O6 octahedra. There are three shorter (2.42 Å) and three longer (2.63 Å) Bi(1)-O(1) bond lengths. P(1) is bonded to four equivalent O(1) atoms to form PO4 tetrahedra that share corners with eight equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-68°. All P(1)-O(1) bond lengths are 1.56 Å. O(1) is bonded in a distorted single-bond geometry to two equivalent Bi(1) and one P(1) atom.
