La3Ga4Cl crystallizes in the tetragonal I4/mcm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 2-coordinate geometry to eight equivalent Ga(1) and two equivalent Cl(1) atoms. In the second La site, La(2) is bonded in a distorted linear geometry to eight equivalent Ga(1) and two equivalent Cl(1) atoms. Ga(1) is bonded in a 9-coordinate geometry to two equivalent La(2), four equivalent La(1), and three equivalent Ga(1) atoms. Cl(1) is bonded to two equivalent La(2) and four equivalent La(1) atoms to form corner-sharing ClLa6 octahedra. The corner-sharing octahedral tilt angles range from 0-39°.
La3Ga4Cl crystallizes in the tetragonal I4/mcm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 2-coordinate geometry to eight equivalent Ga(1) and two equivalent Cl(1) atoms. There are a spread of La(1)-Ga(1) bond distances ranging from 3.23-3.43 Å. Both La(1)-Cl(1) bond lengths are 3.08 Å. In the second La site, La(2) is bonded in a distorted linear geometry to eight equivalent Ga(1) and two equivalent Cl(1) atoms. All La(2)-Ga(1) bond lengths are 3.20 Å. Both La(2)-Cl(1) bond lengths are 2.85 Å. Ga(1) is bonded in a 9-coordinate geometry to two equivalent La(2), four equivalent La(1), and three equivalent Ga(1) atoms. There are two shorter (2.60 Å) and one longer (2.74 Å) Ga(1)-Ga(1) bond length. Cl(1) is bonded to two equivalent La(2) and four equivalent La(1) atoms to form corner-sharing ClLa6 octahedra. The corner-sharing octahedral tilt angles range from 0-39°.
