Some investigations on new polyphosphates by the anion-exchange method.
The structure of the pentamer (a new P-P bonded phosphate) produced by the hydrolysis of dodecaoxohexaphosphoric(III) acid (ring hexamer) has been examined by an anion-exchange distribution method after complex formation with copper(II) and found to be HPO(OH)PO(OH)PO(OH)PO(OH)PO(OH)H. The hexamer and pentamer salts of these P-P bonded linear phosphorus anions have been prepared. The yield of each species was about 1 mole% of the parent material.
