Abstract
The reactivities, or the interactions in nonaqueous media of the Keggin-type heteropolyanions [XM 12O 40] n- (X = Co II, Zn II, Al III, Si, P, 2H +, M = W; X = P, Si, M = Mo) and the Fe(III)-substituted mixed-type polyanions [PFeM 11O 40H 2] 4- (M= Mo, W) with a chiral organic compound such as l-brucine sulphate have been studied using the electronic absorption, differences absorption and CD spectra. Two types of the interaction of l-brucine with the polyanions have been indicated from the observed Cotton effect; one is an outer-sphere association of the brucinium ion with the surface bridged oxygens of dodecametallate and the other a coordination of brucine to the Fe(III) ion in the mixed-type polyanions. In the latter, an outer-sphere association between the PM 11O 39 7- moiety and brucinium ion has been also suggested.
