Characterization of a platinum-substituted keggin anion and studies of robust, hydrogen-bonded polyanion aggregates
… studies of platinotungstate and platinomolybdate heteropolyanions were carried out. Salts of the Keggin-type -SiPtW11O406- anion (1) were prepared through the reaction of K8SiW11O39.13H2O with K2Pt(OH)6 and acidification of the reaction solution to pH 4 with HNO3. Infrared spectra indicated …
