摘 要: | In order to investigate the influence of organic groups on the types of organoarsenic polymolybdates, o-nitrophenylarsonic acid was reduced to o- aminophenylarsonic acid and then it reacted with sodium molybdate at pH = 3~5. Three new salts were prepared and characterized:( 1 ) (CN3H6)4[(o-NH2C6H4As)2Mo6O24], ( 2 ) Cs4[(o-NH2C6H4As)2Mo6O24], (3) [(CH3)4N]4[(o-NH2C6H4As)2Mo6O24].2H2O. The IR, UV spectra, thermal properties and electrochemical behaviors are reported. It is strange enough that when the o-nitro group was reduced to o-amino group, [(RAs)2Mo6O24]4- type of complexes was formed.
