    • In the structural determination, many atoms could not be refined anisotropically (for example, Mo16 and O16, probably due to disorder and/or twinning, and various attempts to improve the structure refinements were unsuccessful. In the final difference map, the deepest hole was -3.41 e Å-3 near the Mo16 position. The highest peak of 4.59 e Å-3 near the P3 position was tested as a P atom, but we obtained an atomic occupancy of almost zero. There was a big void (4400 Å3) in the unit cell, owing to a lot of diffuse solvent (acetonitrile molecules, The existence of ca. 40-50 acetonitrile molecules was estimated in the solvent-accessible void, because one acetonitrile molecule was calculated to occupy ca. 100 Å3. The acetonitrile molecules were easily released from the crystal, and the elemental analysis data were in good agreement with those for (Pr4N)8[(P2O7)2Mo
