Synthesis of homo and hetero metal-phosphonate frameworks from bi-functional aminomethylphosphonic acid
چکیده انگلیسی

The reaction between aminomethylphosphonic acid (ampa) and the metal salts of Zn, Cd, Hg, Pb, Ag, and Cu afforded seven metal-phosphonate polymers with unique structural features and includes the synthesis of a bimetallic metal-organic framework (Cu/Ag). The characterization of these metal phosphonates is reported by means of infrared spectroscopy, 1H-NMR, 31P-NMR, X-ray crystallography, energy dispersive X-ray (EDX), and thermogravimetric analysis (TGA). Individual structural features are compared based on the preferred coordination mode of ampa and the geometrical requirements for each metallic center that manipulates the structural motif.

The synthesis and characterization of polymeric metal phosphonates featuring zinc, cadmium, mercury, lead, and silver phosphonate are described from the reactions of the bi-funtional aminomethylphosphonic acid with the metal precursor in aqueous conditions. These previously undescribed polymers display unusual structural features and include the synthesis of a bimetallic metal-organic framework (Cu/Ag).Figure optionsDownload as PowerPoint slide
