Abstract
Reactions of MoOCl52- with [PW11O39]7- and [SiW11O39]8- have been studied spectrophotometrically and several transient complexes have been discovered. Transient species initially formed are probably [Mo2O4(PW11O39)2]12- and [Mo2O4(SiW11O39)2]14-. Spectra change gradually, indicating formation of transient isomers of [PMoW11O40]4- and [SiMoW11O40]5-, which again transform into the stable isomers. The transient isomers absorb light much more strongly than the stable isomers in the visible range.
