Almost rectangular cavities can be seen in the structure of the title compound (part of the crystal structure shown on the right), the first heteropolyoxo‐tungstate with defined micropores. The compound was prepared in a hydrothermal reaction with W, WO 3 , H 3 PO 4 , H 2 O, and hexamethylenediamine. Potential applications of this compound in catalytic oxidations or as a support in shape‐selective reactions must still be proven.
