Materials Data on Sr(MgIn)2 by Materials Project
Sr(MgIn)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr is bonded in a 8-coordinate geometry to eight equivalent In atoms. All Sr–In bond lengths are 3.62 Å. Mg is bonded to four equivalent In atoms to form a mixture of corner and edge-sharing MgIn4 tetrahedra. All Mg–In bond lengths are 2.97 Å. In is bonded in a 9-coordinate geometry to four equivalent Sr, four equivalent Mg, and one In atom. The In–In bond length is 2.87 Å.
