Abstract: In order to investigate the types of compounds of arylarsenic polymo-lybdates, we have prepared ortho-, meta-, para-nitrophenylarsenic acids and tested the reactions of these acids with sodium molybdate at pH3～5. Five new salts of arylarsenic polymolybdates have been synthesized and characterized, (a) (CN3H6)5 [(o-NO2C6H4As)2Mo6O25H]·H2O, (6) Cs5[(o-NO2C6H4As)2Mo6O25H], (c) (CN3H6)5 [(m-NO2C6H4As)2Mo6O25H]·4H2O, (d) (CN3H6)5 [(p-NO2C6H4As)2Mo6O25H]·4H2O, (e) Cs5[(p-NO2C6H4As)2Mo6O25H].We thus find that different positions of nitro group on benzene ring have little influence on the complex type thus formed.They all belong to [(RAs)2Mo6O25H]5- type, which is different from the [(RAs)2Mo6O24]4- type reported by Kwak et al, but is the same as its phenyl derivative type [(RAs)2Mo6O25H]5-and also the same as its tungsten congener type [(RAs)2W6O25H]5- reported by Wasfi et al,The infrared spectra, ultraviolet spectra and cyclic voltammograms of all these salts have been reported. The infrared spectroscopic and electrochemical anomaly of ortho-nitrophenylarsenic polymolybdates has been discussed .
