Two a-amino acids, 3-phosphono-2-aminopropionic and 4-phosphono-2-aminobutyric, are used to link zinc atoms in three-dimensional structures where the three phosphonic and one of the carboxylic oxygen atoms coordinate to the metal, while the protonated amino groups and the second carboxylic oxygen atom are not coordinated and remain terminal in the voids of the framework.
