摘要

The deep-blue compound Na-48[HxMo368O1032(H2O)(240)(SO4)(48)] (.) ca. 1000H(2)O equivalent to Na-48 1a (.) ca. 1000H(2)O (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 Mo-nu 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 Lis a new crystal structure determination of the very complex system while confirming the earlier one.
