Sr(MgIn)2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 8-coordinate geometry to eight equivalent In(1) atoms. Mg(1) is bonded to four equivalent In(1) atoms to form a mixture of corner and edge-sharing MgIn4 tetrahedra. In(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), four equivalent Mg(1), and one In(1) atom.
