BaLaCl5 crystallizes in the monoclinic P2_1/m space group. Ba(1) is bonded in a 8-coordinate geometry to one Cl(5), two equivalent Cl(1), two equivalent Cl(4), and three equivalent Cl(2) atoms. La(1) is bonded in a 7-coordinate geometry to one Cl(1), one Cl(4), two equivalent Cl(5), and three equivalent Cl(3) atoms. There are five inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 3-coordinate geometry to two equivalent Ba(1) and one La(1) atom. In the second Cl site, Cl(2) is bonded in a trigonal non-coplanar geometry to three equivalent Ba(1) atoms. In the third Cl site, Cl(3) is bonded in a trigonal non-coplanar geometry to three equivalent La(1) atoms. In the fourth Cl site, Cl(4) is bonded in a 3-coordinate geometry to two equivalent Ba(1) and one La(1) atom. In the fifth Cl site, Cl(5) is bonded in a distorted trigonal planar geometry to one Ba(1) and two equivalent La(1) atoms.
