The compound described by MgEuGa3 crystallizes in the tetragonal I-4m2 space group. Mg(1) is bonded in a 8-coordinate geometry to four equivalent Eu(1), four equivalent Ga(1), and four equivalent Ga(2) atoms. Eu(1) is bonded in a 16-coordinate geometry to four equivalent Mg(1), four equivalent Ga(2), and eight equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), four equivalent Eu(1), one Ga(1), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded to four equivalent Mg(1), four equivalent Eu(1), and four equivalent Ga(1) atoms to form a mixture of face and corner-sharing GaEu4Mg4Ga4 cuboctahedra. is represented by the CIF card [CIF]
