Complexes of Keggin phosphomolybdate and phosphotungstate anions with tri- and tetra-peptides, GlyGlyGly and GlyGlyGlyGly respectively, were isolated and investigated by single crystal X-ray diffraction, FTIR and SEM-EDS in the solid state and by H-1- and P-31 NMR and ESI-MS in solution. The trends imposed by longer chain length and increased hydrophobicity of the peptide molecules were traced both in binding in the solid state and in effects on solution stability of POMs. Hydrolysis of peptides was observed in strongly acidic solutions at enhanced temperatures in the presence of tungsten POMs.Keywords
