A novel coordination polymer, poly[4-aminopyridinium [diaqua[mu(3)-5-(carboxylatomethoxy)benzene-1,3-dicarboxylato]cadmium(II)] dihydrate], {(C5H7N2)[Cd(C10H5O7)(H2O)(2)]center dot 2H(2)O}(n) or {(HpAPy)[Cd(OABDC)(H2O)(2)]center dot 2H(2)O}(n) [HpAPy is 4-aminopyridinium and H(3)OABDC 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.
