Streszczenie

The formation of a dimeric VOIV–D-galacturonic acid complex in aqueous solution has been studied by spectroscopic methods, namely e.s.r., electron nuclear double resonance, and electronic absorption. The complex exhibits properties consistent with a metal–metal distance of about 5.0 Å, which is very similar to that found in the well known VOIV–tartrate dimers. The only way to accommodate the metal ions at such a distance and to fit the spectroscopic data is to assume that the ligand co-ordinates to the metal ion through the CO2, O(4) and O(3), O(2) donor sets and adopts an open-chain structure which is stabilized by the dimer complex formation.
