BaLa2Cl8 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded to two equivalent Cl(2), two equivalent Cl(3), and eight equivalent Cl(1) atoms to form distorted face-sharing BaCl12 cuboctahedra. La(1) is bonded in a 8-coordinate geometry to two equivalent Cl(2), two equivalent Cl(3), and four equivalent Cl(1) atoms. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent La(1) atoms. In the second Cl site, Cl(2) is bonded in a trigonal non-coplanar geometry to one Ba(1) and two equivalent La(1) atoms. In the third Cl site, Cl(3) is bonded in a distorted trigonal planar geometry to one Ba(1) and two equivalent La(1) atoms.
BaLa2Cl8 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded to two equivalent Cl(2), two equivalent Cl(3), and eight equivalent Cl(1) atoms to form distorted face-sharing BaCl12 cuboctahedra. Both Ba(1)-Cl(2) bond lengths are 3.30 Å. Both Ba(1)-Cl(3) bond lengths are 3.20 Å. There are four shorter (3.61 Å) and four longer (3.66 Å) Ba(1)-Cl(1) bond lengths. La(1) is bonded in a 8-coordinate geometry to two equivalent Cl(2), two equivalent Cl(3), and four equivalent Cl(1) atoms. Both La(1)-Cl(2) bond lengths are 2.91 Å. Both La(1)-Cl(3) bond lengths are 2.92 Å. There are two shorter (2.92 Å) and two longer (2.93 Å) La(1)-Cl(1) bond lengths. There are three inequivalent Cl sites.
