Materials Data on La3SbI3 by Materials Project

La3SbI3 crystallizes in the cubic I4_132 space group. The structure is three-dimensional. La2+ is bonded to two equivalent Sb3- and four equivalent I1- atoms to form a mixture of edge and corner-sharing LaSb2I4 octahedra. The corner-sharing octahedra tilt angles range from 3–7°. Both La–Sb bond lengths are 3.12 Å. There are two shorter (3.33 Å) and two longer (3.37 Å) La–I bond lengths. Sb3- is bonded to six equivalent La2+ atoms to form edge-sharing SbLa6 octahedra. I1- is bonded in a rectangular see-saw-like geometry to four equivalent La2+ atoms.

Materials Data on La2SbI2 by Materials Project

La2SbI2 is MAX Phase-like structured and crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of one La2SbI2 sheet oriented in the (0, 0, 1) direction. La+2.50+ is bonded to three equivalent Sb3- and three equivalent I1- atoms to form a mixture of edge and corner-sharing LaSb3I3 octahedra. The corner-sharing octahedral tilt angles are 0°. All La–Sb bond lengths are 3.20 Å. All La–I bond lengths are 3.33 Å. Sb3- is bonded to six equivalent La+2.50+ atoms to form edge-sharing SbLa6 octahedra. I1- is bonded in a distorted T-shaped geometry to three equivalent La+2.50+ atoms.
