Bi4(BO4)3 crystallizes in the cubic I-43d space group. B(1) is bonded to four equivalent O(1) atoms to form BO4 tetrahedra that share corners with eight equivalent Bi(1)O6 pentagonal pyramids. Bi(1) is bonded to six equivalent O(1) atoms to form distorted BiO6 pentagonal pyramids that share corners with six equivalent B(1)O4 tetrahedra and edges with three equivalent Bi(1)O6 pentagonal pyramids. O(1) is bonded in a distorted single-bond geometry to one B(1) and two equivalent Bi(1) atoms.
Bi4(BO4)3 crystallizes in the cubic I-43d space group. B(1) is bonded to four equivalent O(1) atoms to form BO4 tetrahedra that share corners with eight equivalent Bi(1)O6 pentagonal pyramids. All B(1)-O(1) bond lengths are 1.48 Å. Bi(1) is bonded to six equivalent O(1) atoms to form distorted BiO6 pentagonal pyramids that share corners with six equivalent B(1)O4 tetrahedra and edges with three equivalent Bi(1)O6 pentagonal pyramids. There are three shorter (2.24 Å) and three longer (2.42 Å) Bi(1)-O(1) bond lengths. O(1) is bonded in a distorted single-bond geometry to one B(1) and two equivalent Bi(1) atoms.
