本文是作者在合成了一系列有机胂、有机(月弟)的钨、钼聚多酸盐后,有关若干有机膦合钼聚多酸“柄状”化合物的合成报导以及一些光学性质的测定。有关有机基团是C_2H_5,n-C_3H_7,n-C_4H_9,n-C_5H_(11)及C_6H_5CH_2。发现pH为3～5时,在不同的投料比例下都只形成一种类型的化合物[(RP)_2Mo_5O_(21)]~(4-),与相应的有机胂衍生物既可形成[(RAs)_2Mo_5O_(21)]~(4-)又可形成[(RAs)_2Mo_6O_(24)]~(4-)有较大的差异。
This article is a synthesis report and some optical properties of some organophosphorus polymolybdate polyacid “handle” compounds synthesized by a series of organoarsenic, organophosphorus, tungsten and molybdenum polyacids. The relevant organic groups are C_2H_5, n_C_3H_7, n-C_4H_9, n-C_5H_ (11) and C_6H_5CH_2. It was found that only one type of compound [(RP) _2Mo_5O_ (21)] ~ (4-) was formed under different feed ratios when the pH was 3 ~ 5, and the corresponding organic arsine derivatives could form [(RAs ) _2Mo_5O_ (21)] ~ (4-) and [(RAs) _2Mo_6O_ (24)] ~ (4-) can form a big difference.
