Pr5C2Cl9 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are five inequivalent Pr3+ sites. In the first Pr3+ site, Pr3+ is bonded in a 9-coordinate geometry to two C3- and seven Cl1- atoms. There are one shorter (2.46 Å) and one longer (2.49 Å) Pr–C bond lengths. There are a spread of Pr–Cl bond distances ranging from 2.91–3.41 Å. In the second Pr3+ site, Pr3+ is bonded in a 8-coordinate geometry to two C3- and six Cl1- atoms. There are one shorter (2.48 Å) and one longer (2.49 Å) Pr–C bond lengths. There are a spread of Pr–Cl bond distances ranging from 2.87–3.24 Å. In the third Pr3+ site, Pr3+ is bonded in a 7-coordinate geometry to one C3- and six Cl1- atoms. The Pr–C bond length is 2.34 Å. There are a spread of Pr–Cl bond distances ranging from 2.86–3.12 Å. In the fourth Pr3+ site, Pr3+ is bonded in a 7-coordinate geometry to two C3- and seven Cl1- atoms. There are one shorter (2.47 Å) and one longer (2.50 Å) Pr–C bond lengths. There are a spread of Pr–Cl bond distances ranging from 2.84–3.47 Å. In the fifth Pr3+ site, Pr3+ is bonded to one C3- and six Cl1- atoms to form a mixture of distorted edge and corner-sharing PrCCl6 pentagonal bipyramids. The Pr–C bond length is 2.33 Å. There are a spread of Pr–Cl bond distances ranging from 2.83–3.14 Å. There are two inequivalent C3- sites.
