The material structure described by Sr4Bi3 crystallizes in the cubic I-43d space group. Sr(1) is bonded to six equivalent Bi(1) atoms to form a mixture of distorted corner, face, and edge-sharing SrBi6 octahedra. The corner-sharing octahedral tilt angles range from 18-49°. Bi(1) is bonded to eight equivalent Sr(1) atoms to form a mixture of distorted corner, face, and edge-sharing BiSr8 hexagonal bipyramids. is represented by the CIF card [CIF]
