LiSm(C2O5)2 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. Li1+ is bonded in a distorted trigonal bipyramidal geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 2.05–2.48 Å. Sm3+ is bonded in a 9-coordinate geometry to eight O2- atoms. There are a spread of Sm–O bond distances ranging from 2.40–2.52 Å. There are five inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.27 Å) C–O bond length. In the second C4+ site, C4+ is bonded in a bent 120 degrees geometry to two equivalent O2- atoms. Both C–O bond lengths are 1.27 Å. In the third C4+ site, C4+ is bonded in a bent 120 degrees geometry to two equivalent O2- atoms. Both C–O bond lengths are 1.27 Å. In the fourth C4+ site, C4+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both C–O bond lengths are 1.27 Å. In the fifth C4+ site, C4+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.28 Å) C–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sm3+ and one C4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Sm3+, and one C4+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+ and one O2- atom. The O–O bond length is 1.23 Å. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sm3+ and one C4+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sm3+ and one C4+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Sm3+, and one C4+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Sm3+, and one C4+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Sm3+, and one C4+ atom. In the ninth O2- site, O2- is bonded in a single-bond geometry to one O2- atom. In the tenth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sm3+ and one C4+ atom.
