Abstract:	No legendary Prussian order! The distribution of vacancies in Prussian blue analogues is not random, and the spin density on the Cd²⁺ ion varies depending on the number of paramagnetic ions in its surroundings. This conclusion follows from ¹¹³Cd solid‐state magic‐angle spinning NMR studies of [Cd₃{Fe/Co(CN)₆}₂]?15 H₂O, where the presence of small but significant spin density on the observed ¹¹³Cd nucleus leads to improved spectral resolution.
