Abstract

Two novel bismuth succinate hydrates, namely, poly[[diaqua(μ₃-butane-1,4-dicarboxylato)hemi(μ-butane-1,4-dicarboxylato)bismuth] monohydrate], {[Bi(C₄H₄O₄)_1.5(H₂O)₂]·H₂O}_n (1), and poly[[μ-aqua-aqua(μ₃-butane-1,4-dicarboxylato)(μ-butane-1,4-dicarboxylato)-μ-oxido-dibismuth] monohydrate], {[Bi₂(C₄H₄O₄)₂O(H₂O)₂]·H₂O}_n (2), have been synthesized. Their crystal structures were determined by single-crystal X-ray diffraction and the compounds were characterized by IR and Raman spectroscopy, powder X-ray diffraction and thermal analysis. The crystal structure analysis revealed that the compounds are coordination polymers, with 1 having a two-dimensional layered structure and 2 displaying a three-dimensional (3D) framework. Fully deprotonated succinate anions (C₄H₄O₄^2-) in two different conformations (trans and gauche) are included in their composition. The Bi³⁺ cations are surrounded by O atoms from the carboxylate groups of succinate anions and aqua ligands. BiO₉ coordination polyhedra in 1 are connected in pairs by edges. These pairs are bound together by bridging succinate ligands to form layers. Bismuth coordination polyhedra of two different types (BiO₉ and BiO₇) in 2 are connected by edges to form infinite ribbons. Ribbons of polyhedra with bridging succinate ligands form a 3D polymeric structure.

两种新的琥珀酸铋盐：合成、结构、光谱和热表征。

合成了两种新型的琥珀酸铋水合物，即聚[[二夸（μ3-丁烷-1,4-二羧酸酯）半（μ-丁烷-1,4-双羧酸酯）铋]一水合物]、{[Bi（C4H4O4）1.5（H2O）2]·H2O}n（1）和聚[[μ-水（μ3-丁-1,4-二甲酸酯）（μ-丁-1,4-双甲酸酯）-μ-氧化二铋]一水合物]、{Bi2（C4H4SO4）2O（H2O）2]·H2O}n（2）。通过单晶X射线衍射测定了它们的晶体结构，并通过红外光谱、拉曼光谱、粉末X射线衍射和热分析对化合物进行了表征。晶体结构分析表明，这些化合物是配位聚合物，其中1具有二维层状结构，2显示三维（3D）骨架。在它们的组合物中包括两种不同构象（反式和gauche）的完全去质子化的琥珀酸阴离子（C4H4O42-）。Bi3+阳离子被琥珀酸酯阴离子和水性配体的羧酸根的O原子包围。1中的BiO9配位多面体通过边成对连接。这些对通过桥接琥珀酸配体结合在一起形成层。2中两种不同类型的铋配位多面体（BiO9和BiO7）通过边连接形成无限带。具有桥接琥珀酸配体的多面体的带状物形成3D聚合物结构。

期刊介绍： Acta Crystallographica Section C: Structural Chemistry is continuing its transition to a journal that publishes exciting science with structural content, in particular, important results relating to the chemical sciences. Section C is the journal of choice for the rapid publication of articles that highlight interesting research facilitated by the determination, calculation or analysis of structures of any type, other than macromolecular structures. Articles that emphasize the science and the outcomes that were enabled by the study are particularly welcomed. Authors are encouraged to include mainstream science in their papers, thereby producing manuscripts that are substantial scientific well-rounded contributions that appeal to a broad community of readers and increase the profile of the authors.
