The structures of the complex of 2,2'-(methylimino)bis(,-dioctylacetamide) (MIDOA) with M(VII)O (M=Re and Tc), which were prepared by liquid-liquid solvent extraction, were investigated by using H-NMR, EXAFS and IR spectroscopy. The results from H-NMR and EXAFS provide therefore evidence of M(VII)O...HMIDOA complex formation in the organic solution. The IR spectra of Re(VII)O...HMIDOA and Tc(VII)O...HMIDOA were analyzed based on the structures and the IR spectra calculated at the B3LYP/cc-pVDZ level. Comparison of the observed and calculated IR spectra demonstrates that an intramolecular hydrogen bond is formed in HMIDOA and the M(VII)O ion interact with HMIDOA through multiple C-H...O hydrogen bonds.
