“…pertaining under lower nitrate concentrations 8. This conclusion was supported by Wylie who reported the extraction of the hexanitrato anion only at high acid concentrations, inferring the existence of hydrolyzed Ce‐OH complexes at lower acidity 9. Even more unorthodox were the findings published by Blaustein and Gryder about a decade earlier, asserting that polymeric hydrolyzed Ce–Ce complexes are the dominant extracted species even at high (5.5 M ) concentrations of nitric acid 10.…”

Ceric ammonium nitrate (CAN) is a single‐electron‐transfer reagent with unparalleled utility in organic synthesis, and has emerged as a vital feedstock in diverse chemical industries. Most applications use CAN in solution where it is assigned a monomeric [CeIV(NO3)6]2− structure; an assumption traced to half‐century old studies. Using synchrotron X‐rays and Raman spectroscopy we challenge this tradition, converging instead on an oxo‐bridged dinuclear complex, even in strong nitric acid. Thus, one equivalent of CAN is recast as a two‐electron‐transfer reagent and a redox‐activated superbase, raising questions regarding the origins of its reactivity with organic molecules and giving new fundamental insight into the stability of polynuclear complexes of tetravalent ions.

“…The extraction of cerium(IV) by butyl acetate ( 223), diethyl ether (38), diisopropyl ether (37) and nitromethane (443) has been noted. It is usually assumed that the species extracted by ether is (H(solvated))2+ Ce(N03)e, following Wylie's suggestion (451) (but he also suggested 0ß( 03)3). However, Blaustein and Bryder (37) showed that no ionizable protons accompany the cerium into the ether, so that a directly solvated species such as Ce (ether) 2(N03)4 is the main form of cerium in the organic phase.…”

[10] Although these hydrolyzed polynuclear species were largely refuted by the subsequent direct spectroscopic studies, [7] recent literature on the generation of nanoparticles and formate clusters from aqueous Ce IV nitrate solutions suggests the presence of polynuclear oxo-bridged precursor clusters.…”
