A Route to the Synthesis of Trivalent Transition‐Metal Porous Carboxylates with Trimeric Secondary Building Units

Prefabricated construction techniques: A solvothermal route involving iron (III) trimeric secondary building units has been developed. Two new open-framework iron (III) dicarboxylates have been characterized from X-ray powder diffraction studies. Their 3D structures are built up from trimers of iron polyhedra related through dicarboxylates, thus creating cationic frameworks with 1D pore systems filled with solvent molecules and anions (see example).
