Isopolyoxometalates of antimony: Arylstibonic acids [H8(RSb) 12O28] and derived dodecanuclear polyoxostibonates [M 2H10- x(RSb)12O30]x-, M = Na or K

Electrospray ionization mass spectrometry shows arylstibonic acids, p-XC6H4SbO3H2 (X = methyl, nitro, or chloro), and 1-naphthylstibonic acid exist in MeCN as dodecanuclear aggregates [H8(RSb)12O28]. With KOH or NaOH these form polyoxometalate ions [M2H8(RSb)12O 30]2- (M = K or Na) with a hexagonal antiprismatic array of the Sb atoms, as shown by X-ray crystallographic structures for three new examples. There is one firmly encapsulated 10-coordinate M+ ion within an inorganic 12-crown-6 moiety {Sb6O6} in the hexagonal channel and one six-coordinate M+.
