The Al(III)-containing polyanions [Al(III)4(H2O)10(β-XW9O33H)2](4-) with X = As(III) (1) and Sb(III) (2) feature four aluminum(III) centers sandwiched by two trivacant (β-XW9O33) Keggin units, and trigger peroxide catalysis as well as substrate coordination via multiple Lewis acid site interactions.

- The study synthesized a series of polyanions containing cobalt(II), manganese(II), nickel(II), and vanadium(V) ions, characterized through various analytical techniques including XRD and spectroscopy.
- Each polyanion, derived from a superlacunary tungstophosphate structure, demonstrated distinct electrochemical properties and interactions with their respective metal centers, providing insights into their potential applications.
- Magnetic studies indicated that the metal ions in these polyanions behave as noninteracting entities, with temperature and magnetic field dependence analyzed via SQUID magnetometry and EPR measurements.
