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.
在标题配位聚合物{[Sm₂(C₄H₂O₄)₃(H₂O)₆]·6H₂O}ₙ中,Sm(III)离子由来自三个不同马来酸酯配体的四个O原子、来自一个富马酸酯配体的两个O原子和来自三个水分子的三个O原子九配位。富马酸酯配体位于一个对称中心上。相邻的Sm(III)离子由马来酸酯和富马酸酯配体桥连,形成平行于(011)的层。这些层通过分子间O—H⋯O氢键进一步连接成三维超分子网络。
