摘要

在水热条件下合成了一种新型配位聚合物聚[4-氨基吡啶[双水][μ3-5-(羧基甲氧基)苯-1,3-二羧基]镉(II)]二水合物,{(C5H7N2)[Cd(C10H5O7)(H2O)2]·2H2O}n或{(HpAPy)[Cd(OABDC)(H2O)2]·2H2O}n [HpAPy为4-氨基吡啶,H3OABDC为5-(羧基甲氧基)苯-1,3-二羧酸]。单晶分析表明,阴离子配合物具有中心对称的一维管状排列。4-氨基吡啶分子的吡啶N原子被质子化,这个阳离子平衡了管状阴离子配位聚合物的电荷。邻近的管子通过涉及溶剂水分子和OABDC(3-)配体的多个氢键交联成三维框架。

A novel one-dimensional tubular cadmium(II) coordination polymer based on 5-(carboxylatomethoxy)benzene-1,3-dicarboxylate containing 4-aminopyridinium ions.

A novel coordination polymer, poly[4-aminopyridinium [diaqua[μ3-5-(carboxylatomethoxy)benzene-1,3-dicarboxylato]cadmium(II)] dihydrate], {(C5H7N2)[Cd(C10H5O7)(H2O)2]·2H2O}n or {(HpAPy)[Cd(OABDC)(H2O)2]·2H2O}n [HpAPy is 4-aminopyridinium and H3OABDC is 5-(carboxymethoxy)benzene-1,3-dicarboxylic acid], was synthesized under hydrothermal conditions. Single-crystal analysis revealed that the anionic complex has a centrosymmetric one-dimensional tubular arrangement. The pyridine N atom of the 4-aminopyridine molecule is protonated and this cation balances the charge of the tubular anionic coordination polymer. Neighbouring tubes are crosslinked into a three-dimensional framework through multiple hydrogen bonds involving solvent water molecules and OABDC(3-) ligands.

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.
