Abstract

The framework materials [W(72)Mn(II/III)(12)O(268)X(7)](52-/40-) undergo heteroatom (X)-controlled reversible SC-SC redox reactions whereby the Ge-templated framework reduction is fast and reoxidation is slow. The opposite trend is set for the Si-templated framework, and these processes can be followed optically, spectroscopically and crystallographically.
