The structure described by EuAu3Ga4 crystallizes in the tetragonal P4/mmm space group. Eu(1) is bonded in a 16-coordinate geometry to eight equivalent Au(1) and eight equivalent Ga(1) atoms. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1), one Au(1), and four equivalent Ga(1) atoms. In the second Au site, Au(2) is bonded in a body-centered cubic geometry to eight equivalent Ga(1) atoms. Ga(1) is bonded to two equivalent Eu(1), two equivalent Au(1), and two equivalent Au(2) atoms to form a mixture of corner, edge, and face-sharing GaEu2Au4 tetrahedra. is represented by the CIF file [CIF]
