The structure described by Ta3Ga2 crystallizes in the tetragonal P4/mbm space group. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 6-coordinate geometry to six equivalent Ga(1) atoms. In the second Ta site, Ta(2) is bonded in a square co-planar geometry to four equivalent Ga(1) atoms. Ga(1) is bonded in a 9-coordinate geometry to two equivalent Ta(2), six equivalent Ta(1), and one Ga(1) atom. is represented by the CIF card [CIF]
