The material structure described by Eu(MgGa)2 crystallizes in the tetragonal I4/mmm space group. Mg(1) is bonded to four equivalent Ga(1) atoms to form MgGa4 tetrahedra that share corners with eight equivalent Eu(1)Ga8 hexagonal bipyramids, corners with four equivalent Mg(1)Ga4 tetrahedra, edges with four equivalent Eu(1)Ga8 hexagonal bipyramids, and edges with four equivalent Mg(1)Ga4 tetrahedra. Eu(1) is bonded to eight equivalent Ga(1) atoms to form distorted EuGa8 hexagonal bipyramids that share corners with sixteen equivalent Mg(1)Ga4 tetrahedra, edges with four equivalent Eu(1)Ga8 hexagonal bipyramids, edges with eight equivalent Mg(1)Ga4 tetrahedra, and faces with four equivalent Eu(1)Ga8 hexagonal bipyramids. Ga(1) is bonded in a 9-coordinate geometry to four equivalent Mg(1), four equivalent Eu(1), and one Ga(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
