Abstract: 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, UVspectra, 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.

Key words: o-Aminophenylarsonic acid, Polymolybdates, Polytungstates
