The crystal structure described by Ba2LaCl7 crystallizes in the monoclinic C2/c space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 7-coordinate geometry to one Cl(1), one Cl(3), one Cl(4), one Cl(5), and three equivalent Cl(7) atoms. In the second Ba site, Ba(2) is bonded in a 8-coordinate geometry to one Cl(1), one Cl(2), one Cl(3), one Cl(4), one Cl(5), one Cl(7), and two equivalent Cl(6) atoms. La(1) is bonded in an octahedral geometry to one Cl(1), one Cl(2), one Cl(3), one Cl(4), one Cl(5), and one Cl(6) atom. There are seven inequivalent Cl sites. In the first Cl site, Cl(7) is bonded to one Ba(2) and three equivalent Ba(1) atoms to form a mixture of corner and edge-sharing ClBa4 tetrahedra. In the second Cl site, Cl(1) is bonded in a trigonal non-coplanar geometry to one Ba(1), one Ba(2), and one La(1) atom. In the third Cl site, Cl(2) is bonded in a distorted L-shaped geometry to one Ba(2) and one La(1) atom. In the fourth Cl site, Cl(3) is bonded in a 3-coordinate geometry to one Ba(1), one Ba(2), and one La(1) atom. In the fifth Cl site, Cl(4) is bonded in a distorted T-shaped geometry to one Ba(1), one Ba(2), and one La(1) atom. In the sixth Cl site, Cl(5) is bonded in a distorted trigonal non-coplanar geometry to one Ba(1), one Ba(2), and one La(1) atom. In the seventh Cl site, Cl(6) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ba(2) and one La(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
