The structure described by BaLa2Cl8 crystallizes in the monoclinic C2/c space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent Cl(1), two equivalent Cl(4), and four equivalent Cl(2) atoms. La(1) is bonded to one Cl(1), one Cl(2), two equivalent Cl(3), and two equivalent Cl(4) atoms to form a mixture of distorted corner and edge-sharing LaCl6 octahedra. The corner-sharing octahedral tilt angles are 48°. There are four inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a bent 150 degrees geometry to one Ba(1) and one La(1) atom. In the second Cl site, Cl(2) is bonded in a distorted trigonal planar geometry to two equivalent Ba(1) and one La(1) atom. In the third Cl site, Cl(3) is bonded in a bent 120 degrees geometry to two equivalent La(1) atoms. In the fourth Cl site, Cl(4) is bonded in a distorted trigonal non-coplanar geometry to one Ba(1) and two equivalent La(1) atoms. is represented by the CIF file [CIF]
