Abstract: The title compound, [Sm₂(C₁₄H₈O₄)₃(H₂O)₂]_n, is composed of one-dimensional chains and is isostructural with previously reported compounds [Wang et al. (2003). Eur. J. Inorg. Chem. pp. 1355-1360]. The asymmetric unit contains two Sm atoms, each of which lies on a crystallographic twofold axis. Both crystallographically independent Sm atoms are coordinated by eight O atoms in a distorted dodecahedral arrangement. The polymeric chains run along [001]. Adjacent chains are connected through - interactions [centroid-centroid distance = 3.450 (2) Å], forming a two-dimensional supramolecular network.
