Materials Data on La3Ga4Cl by Materials Project
La3Ga4Cl crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent La sites. In the first La site, La is bonded in a 2-coordinate geometry to eight equivalent Ga and two equivalent Cl atoms. There are a spread of La–Ga bond distances ranging from 3.23–3.45 Å. Both La–Cl bond lengths are 3.10 Å. In the second La site, La is bonded in a distorted linear geometry to eight equivalent Ga and two equivalent Cl atoms. All La–Ga bond lengths are 3.23 Å. Both La–Cl bond lengths are 2.86 Å. Ga is bonded in a 9-coordinate geometry to six La and three equivalent Ga atoms. There are two shorter (2.64 Å) and one longer (2.76 Å) Ga–Ga bond lengths. Cl is bonded to six La atoms to form corner-sharing ClLa6 octahedra. The corner-sharing octahedra tilt angles range from 0–39°.
