    Three porous metal–organic frameworks {[Ni­(H<sub>2</sub>BTTB)·(H<sub>2</sub>O)<sub>2</sub>]·(DIOX)<sub>2</sub>}<i><sub>n</sub></i> (<b>1</b>), {[Zn­(H<sub>2</sub>BTTB)]·(DEF)<sub>3</sub>·(H<sub>2</sub>O)<sub>2</sub>}<sub><i>n</i></sub> (<b>2</b>), and {[Mg­(H<sub>2</sub>BTTB)·(C<sub>2</sub>H<sub>5</sub>OH)<sub>2</sub>]·(DEF)<sub>4</sub>}<i><sub>n</sub></i> (<b>3</b>) based on the 4,4′,4″,4‴-benzene-1,2,4,5-tetrayltetrabenzoic acid (H<sub>4</sub>BTTB) ligand have been synthesized under solvothermal conditions (DIOX = dioxane). These three MOFs show structural diversities: compound <b>1</b> is a two-dimensional (2D) grid layer, compound <b>2</b> is a 2-fold interpenetrated 3D framework with a pillared-layer structure, and compound <b>3</b> is a noninterpenetrated 3D framework with a (4, 4)-connected binodal net. Compound <b>1</b> and compound <b>2</b> have BET surface areas of 391 and 447 m<sup>2</sup>/g, respectively; however, the surface area of compound <b>3</b> cannot be experimentally determined. All three MOFs have a higher adsorption preference for CO<sub>2</sub> over N<sub>2</sub> and CH<sub>4</sub>. Ideal adsorbed solution theory was used to estimate binary adsorption selectivities. Compound <b>2</b> shows the highest capacity for all three gases, whereas compound <b>1</b> shows the highest selectivity for CO<sub>2</sub> over CH<sub>4</sub> and N<sub>2</sub>. Compound <b>1</b> exhibits a selectivity of ∼30 for CO<sub>2</sub> over N<sub>2</sub> in equimolar mixtures
