Abstract
The deep-blue compound Na48[HxMo368O1032(H2O)240(SO4)48] · ca. 1000H2O = Na48 1a · ca. 1000H2O (1) exhibiting an unusual nanosized hedgehog-type cluster anion, could now be obtained in good yield - allowing now several materials science studies - in the presence of a high concentration of an electrolyte destroying the hydration shell, in only two days. 1 was characterized by elemental analysis (including redox titrations to determine the (formal) number of MoV centers), thermogravimetry and spectroscopic methods (IR, resonance Raman, Vis/NIR). Information about unusual aspects of the formation is reported together with additional spectroscopic details as well as a new crystal structure determination of the very complex system while confirming the earlier one.
