We have retrieved from the Cambridge Structural Database (CSD), the Inorganic Crystal Structure Database (ICSD) and the Protein Data Bank (PDB) decavanadate based compounds, in order to find intermolecular interactions between decavanadate oxygen atom and different proton donor type (D = O, N, C). 63 different structures have been found containing decavanadate anion, leading to 2975 intermolecular contacts belonging to the 48 structures for which the hydrogen bonds have been localised. In a previous study, (Bosnjakovic-Pavlovic et al., Inorg. Chem., 2009) we have predicted the preferential noncovalent interactions with the different oxygen atoms of the decavanadate anion. These predictions are confirmed, in the present study. Noncovalent interactions are strongly different as a function of the oxygen atom type. The Ob, triply-linked, and Oc, double-linked oxygen atoms, for which the electrostatic potential in the vicinity have the lowest value, are mainly involved in the strong as O-H⋅⋅⋅O, N-H⋅⋅⋅O interactions, while the mono linked Of or Og are mainly involved in weakest noncovalent interactions such as C-H⋅⋅⋅O or cation interactions. Binding properties of decavanadate anion in biological systems are illustrated using PDB. Anion binding behaviour in small-molecule structures and in macromolecular structures is in good agreement. These results are important in the context of the various biological applications of the decavanadate such as, for example, inhibition of the Ca 2+ ATPase, myosin ATPase, and new development in insulin mimetic.
