Materials Data on La3Cl by Materials Project
La3Cl crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent La sites. In the first La site, La is bonded in a 12-coordinate geometry to four equivalent Cl atoms. All La–Cl bond lengths are 3.64 Å. In the second La site, La is bonded in a square co-planar geometry to four equivalent Cl atoms. All La–Cl bond lengths are 3.40 Å. Cl is bonded to twelve La atoms to form a mixture of face, edge, and corner-sharing ClLa12 cuboctahedra.
