Ce3Ga4Cl crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 2-coordinate geometry to eight equivalent Ga(1) and two equivalent Cl(1) atoms. In the second Ce site, Ce(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 Ce(2), four equivalent Ce(1), and three equivalent Ga(1) atoms. Cl(1) is bonded to two equivalent Ce(2) and four equivalent Ce(1) atoms to form corner-sharing ClCe6 octahedra. The corner-sharing octahedral tilt angles range from 0-39°.
Ce3Ga4Cl crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 2-coordinate geometry to eight equivalent Ga(1) and two equivalent Cl(1) atoms. There are a spread of Ce(1)-Ga(1) bond distances ranging from 3.15-3.39 Å. Both Ce(1)-Cl(1) bond lengths are 3.03 Å. In the second Ce site, Ce(2) is bonded in a distorted linear geometry to eight equivalent Ga(1) and two equivalent Cl(1) atoms. All Ce(2)-Ga(1) bond lengths are 3.15 Å. Both Ce(2)-Cl(1) bond lengths are 2.81 Å. Ga(1) is bonded in a 9-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), and three equivalent Ga(1) atoms. There are two shorter (2.59 Å) and one longer (2.69 Å) Ga(1)-Ga(1) bond length. Cl(1) is bonded to two equivalent Ce(2) and four equivalent Ce(1) atoms to form corner-sharing ClCe6 octahedra. The corner-sharing octahedral tilt angles range from 0-39°.
