metal-organic compounds
A novel anionic tubular CdII coordination polymer based on the 5-(carboxylatomethoxy)benzene-1,3-dicarboxylate ligand and containing 4-aminopyridinium cations had been synthesized under hydrothermal conditions. In the solid state, the 4-aminopyridinium cation props up the structure through hydrogen bonds to the O-atom acceptors of ligands and solvent water molecules.
