Abstract
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.
