The compound described by Ta5Sb4 crystallizes in the tetragonal I4/m space group. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 9-coordinate geometry to four equivalent Ta(1) and five equivalent Sb(1) atoms. In the second Ta site, Ta(2) is bonded in a body-centered cubic geometry to eight equivalent Sb(1) atoms. Sb(1) is bonded in a 7-coordinate geometry to two equivalent Ta(2) and five equivalent Ta(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
