The material structure described by Pr4C2Cl5 crystallizes in the orthorhombic Immm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 7-coordinate geometry to one C(1) and six equivalent Cl(1) atoms. In the second Pr site, Pr(2) is bonded to four equivalent C(1), two equivalent Cl(1), and two equivalent Cl(2) atoms to form a mixture of distorted corner, edge, and face-sharing PrC4Cl4 hexagonal bipyramids. C(1) is bonded in a 6-coordinate geometry to one Pr(1), four equivalent Pr(2), and one C(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted rectangular see-saw-like geometry to one Pr(2) and three equivalent Pr(1) atoms. In the second Cl site, Cl(2) is bonded in a square co-planar geometry to four equivalent Pr(2) atoms. is represented by the CIF file [CIF]
