Cationic and mixed-valent forms of Fe3O(CO2)6 trigonal prismatic clusters have been linked by ditopic links, namely, 1,4-benzenedicarboxylate (1,4-BDC) and 1,3-benzenedicarboxylate (1,3-BDC), to produce two 3-periodic metal−organic frameworks (MOFs), [Fe3O(1,4-BDC)3(DMF)3][FeCl4]·(DMF)3 (MOF-235) and Fe3O(1,3-BDC)3(py)3·(py)0.5(H2O)1.5 (MOF-236) (DMF = N,N-dimethylformamide, py = pyridine), respectively. These MOFs exemplify a new, high-symmetry topology termed acs which we identify here as the default arrangement for linking trigonal prisms together.
