Stable metal-organic frameworks with zeolite-like permanent porosity were prepared by using multidentate organic building blocks (including 1,4-benzenedicarboxylate (BDC)) which contribute to the creation of molecular metal-carboxylate secondary building units perfect for the formation of open non-interpenetrated networks. These building blocks facilitated the production of frameworks with zeolitic sorption behavior and permanent microporosity. Examples extracted from the chemistry of BDC demonstrated that Zn(BDC) clusters result in the generation of rigid, stable and truly microporous metal-carboxylate networks. Measurements of gas (benzene, cyclohexane, CCl4, CH2Cl2, etc.) sorption isotherms for this material exhibited type (I) gas uptake that is analogous to those seen in zeolites and molecular sieves.
