BaGa4 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a 16-coordinate geometry to eight equivalent Ga(1) and eight equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to four equivalent Ba(1), one Ga(1), and four equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Ga(1) atoms.
