Materials Data on LaMgI5 by Materials Project
MgLaI5 crystallizes in the orthorhombic Cmcm space group. The structure is two-dimensional and consists of two MgLaI5 sheets oriented in the (0, 1, 0) direction. Mg2+ is bonded to six I1- atoms to form edge-sharing MgI6 octahedra. There are two shorter (2.94 Å) and four longer (2.96 Å) Mg–I bond lengths. La3+ is bonded in a 8-coordinate geometry to eight I1- atoms. There are a spread of La–I bond distances ranging from 3.17–3.52 Å. There are three inequivalent I1- sites. In the first I1- site, I1- is bonded in a 3-coordinate geometry to one Mg2+ and two equivalent La3+ atoms. In the second I1- site, I1- is bonded in a 2-coordinate geometry to two equivalent Mg2+ and one La3+ atom. In the third I1- site, I1- is bonded in an L-shaped geometry to two equivalent La3+ atoms.
