The crystal structure described by La4C2Cl5 crystallizes in the triclinic P-1 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 7-coordinate geometry to one C(1), three equivalent Cl(1), and three equivalent Cl(2) atoms. In the second La site, La(2) is bonded in a 8-coordinate geometry to four equivalent C(1), one Cl(1), one Cl(2), and two equivalent Cl(3) atoms. C(1) is bonded in a 6-coordinate geometry to one La(1), four equivalent La(2), and one C(1) atom. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted rectangular see-saw-like geometry to one La(2) and three equivalent La(1) atoms. In the second Cl site, Cl(2) is bonded in a distorted rectangular see-saw-like geometry to one La(2) and three equivalent La(1) atoms. In the third Cl site, Cl(3) is bonded in a square co-planar geometry to four equivalent La(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
