title: Poly[[hexa-aqua-(μ(2)-fumarato-κO,O:O,O)bis-(μ(3)-maleato-κO,O:O:O)disamarium(III)] hexa-hydrate].
abstract: In the title coordination polymer, {[Sm(2)(C(4)H(2)O(4))(3)(H(2)O)(6)]·6H(2)O}(n), the Sm(III) ion is nine-coordinated by four O atoms from three different maleate ligands, two O atoms from one fumarate ligand and three O atoms from three water mol-ecules. The fumarate ligand lies on an inversion center. Adjacent Sm(III) ions are bridged by the maleate and fumarate ligands, forming a layer parallel to (011). The layers are further linked by inter-molecular O-H⋯O hydrogen bonds into a three-dimensional supra-molecular network.
