The structure described by Ta5Ge3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 6-coordinate geometry to two equivalent Ge(2) and four equivalent Ge(1) atoms. In the second Ta site, Ta(2) is bonded in a 6-coordinate geometry to two equivalent Ta(2) and four equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 10-coordinate geometry to two equivalent Ta(2) and eight equivalent Ta(1) atoms. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to eight equivalent Ta(1) and two equivalent Ge(2) atoms. is represented by the CIF file [CIF]
