Abstract The solvothermal synthesis of a novel mixed‐s‐block metal–organic framework is described, with crystallization brought about by use of the sodium salt of the benzo‐(1,2;3,4;5,6)‐tris(thiophene‐2′‐carboxylate) linker in combination with a lithium salt. The structure of the material was determined by single‐crystal X‐ray diffraction, which reveals an expanded version of the β‐cristobalite topology, with supertetrahedral building units made up of clusters of sodium and lithium ions. Outgassing under vacuum gives permanent porosity to the solid structure with a BET surface area of 1191 m 2 g –1 measured by nitrogen adsorption.
