The addition of H 3 PW 12 O 40 to an aqueous solution of K 2 CrO 4 led to the hydrolysis of [PW 12 O 40 ] 3– with its quantitative conversion into K 13 [KP 2 W 20 O 72 ]. K 13 [KP 2 W 20 O 72 ] in these chromate‐containing solutions was characterized by 183 W and 31 P NMR, EXAFS, SAXS, and EPR spectroscopy.
