La5C2Cl9 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are five inequivalent La3+ sites. In the first La3+ site, La3+ 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) La–C bond lengths. There are a spread of La–Cl bond distances ranging from 2.96–3.37 Å. In the second La3+ site, La3+ is bonded in a 1-coordinate geometry to one C3- and seven Cl1- atoms. The La–C bond length is 2.36 Å. There are a spread of La–Cl bond distances ranging from 2.89–3.41 Å. In the third La3+ site, La3+ is bonded in a 9-coordinate geometry to two C3- and seven Cl1- atoms. There are one shorter (2.46 Å) and one longer (2.51 Å) La–C bond lengths. There are a spread of La–Cl bond distances ranging from 2.88–3.51 Å. In the fourth La3+ site, La3+ is bonded in a 7-coordinate geometry to one C3- and six Cl1- atoms. The La–C bond length is 2.35 Å. There are a spread of La–Cl bond distances ranging from 2.86–3.12 Å. In the fifth La3+ site, La3+ 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) La–C bond lengths.
