Ca-O bond is strengthened by carboxylate ligand with an intramolecular NH...O hydrogen bond. A novel NH...O hydrogenbonded polymer, poly[ 1 -carboxylato-2-(1 -ethoxycarbonyl-3 methylsulfanylpropylcarbamoyl)-ethylene-alt-ethylene] exhibits higher adhesion force on the surface of calcium phosphate crystals than the non-NH...O one.
