Inorganic Synzymes : Convergent structural, spectroscopic, and mechanistic evidence is presented on the bio‐inspired catalysis by Fe III ‐substituted polyoxotungstates [Fe 4 (H 2 O) 10 (β‐XW 9 O 33 ) 2 ] n − (X=As III , Sb III , Se IV , Te IV ) in promoting the aerobic cleavage of catechols (see figure). These polyanions display two of the four iron sites with three external and substitution‐labile coordination positions typical of non‐heme dioxygenase enzymes.
