The crystal structure described by Ba5Sb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 3-coordinate geometry to five equivalent Sb(1) atoms. In the second Ba site, Ba(2) is bonded to six equivalent Sb(1) atoms to form a mixture of distorted edge, face, and corner-sharing BaSb6 octahedra. The corner-sharing octahedral tilt angles are 35°. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Ba(2) and five equivalent Ba(1) atoms. is represented by the CIF file [CIF]
