catena-poly[[[diaqua[trans-3-(4-pyridyl)acrylato]samarium(III)]-di-mu-trans-3-(4-pyridyl)acrylato] dihydrate].
In the title compound, {[Sm(4-pya)(3)(H(2)O)(2)].2H(2)O}(n) [4-pya is trans-3-(4-pyridyl)acrylate, C(8)H(6)NO(2)], each Sm(III) atom is ten-coordinated and has a bicapped square-antiprismatic coordination geometry. There is a crystallographic center of symmetry at the mid-point of the Sm...Sm line within each [Sm(4-pya)(3)(H(2)O)(2)](2) dimer. Each dimer is interconnected by two pairs of bridging 4-pya ligands to form a one-dimensional chain. Neighboring chains are connected via hydrogen bonds to form a three-dimensional network.
