Materials Data on Ba(MgIn)2 by Materials Project
Ba(MgIn)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ba is bonded in a 8-coordinate geometry to eight equivalent Mg and eight equivalent In atoms. All Ba–Mg bond lengths are 4.00 Å. All Ba–In bond lengths are 3.75 Å. Mg is bonded to four equivalent Ba and four equivalent In atoms to form a mixture of corner, edge, and face-sharing MgBa4In4 tetrahedra. All Mg–In bond lengths are 2.99 Å. In is bonded in a 9-coordinate geometry to four equivalent Ba, four equivalent Mg, and one In atom. The In–In bond length is 2.90 Å.
