Materials Data on MgIn2 by Materials Project

MgIn2 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of one MgIn2 ribbon oriented in the (0, 1, 1) direction. Mg is bonded in a 4-coordinate geometry to four In atoms. There are a spread of Mg–In bond distances ranging from 2.81–3.01 Å. There are two inequivalent In sites. In the first In site, In is bonded in a 2-coordinate geometry to two equivalent Mg atoms. In the second In site, In is bonded in a 2-coordinate geometry to two equivalent Mg atoms.

Materials Data on MgIn2 by Materials Project

MgIn2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Mg is bonded in a 12-coordinate geometry to twelve equivalent In atoms. All Mg–In bond lengths are 3.60 Å. In is bonded to six equivalent Mg and six equivalent In atoms to form a mixture of distorted corner, edge, and face-sharing InMg6In6 cuboctahedra. All In–In bond lengths are 3.07 Å.
