A new molybdophosphate (NH4)(8){Mo (2) (V) O-4[(Mo (2) (VI) O-6)CH3C(O)(PO3)(2)](2)}center dot 14H(2)O (1), has been synthesized by the reaction of {Mo (2) (V) O-4(H2O)(6)}(2+) fragments with 1-hydroxyethylidenediphosphonate (hedp HOC(CH3)(PO3H2)(2)), and it is characterized by P-31 NMR, IR, UV, element analysis, TG and single-crystal X-ray analysis. The structure analysis reveals that the polyoxoanion can be described as two {(Mo (2) (VI) O-6)(CH3C(O)(PO3)(2)} units connected by a {Mo (2) (V) O-4}(2+) moiety. In the structure, the six Mo atoms are arranged into a new "W-shaped" structure, which represents a new kind of molybdophosphate.
