The material structure described by EuGa4 crystallizes in the tetragonal I4/mmm space group. Eu(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 Eu(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 Eu(1) and four equivalent Ga(1) atoms. is represented by the CIF card [CIF]
