Arylstibonic acids [H8(RSb)12O28]; precursors to organometallic isopolyoxostibonates [Na2H9(RSb)12O(30)]-, (R = aryl).
Electrospray ionisation mass spectrometry shows that arylstibonic acids, RSbO(3)H(2), give rise to oxo-bridged clusters derived from [H(8)(RSb)(12)O(28)] which act as inorganic crown ligands towards Na(+) cations; structure determination of one derivative revealed a cage-like anion [Na(2)H(9)(p-O(2)NC(6)H(4)Sb)(12)O(30).4H(2)O](-).
