An isomorphous series of 10 microporous copper-based metal-organic frameworks (MOFs) with the general formulas (∞)(3)[{Cu(3)(μ(3)-OH)(X)}(4){Cu(2)(H(2)O)(2)}(3)(H-R-trz-ia)(12)] (R = H, CH(3), Ph; X(2-) = SO(4)(2-), SeO(4)(2-), 2 NO(3)(2-) (1-8)) and (∞)(3)[{Cu(3)(μ(3)-OH)(X)}(8){Cu(2)(H(2)O)(2)}(6)(H-3py-trz-ia)(24)Cu(6)]X(3) (R = 3py; X(2-) = SO(4)(2-), SeO(4)(2-) (9, 10)) is presented together with the closely related compounds (∞)(3)[Cu(6)(μ(4)-O)(μ(3)-OH)(2)(H-Metrz-ia)(4)]Cu(H(2)O)(6)(2)·10H(2)O (11) and (∞)(3)[Cu(2)(H-3py-trz-ia)(2)(H(2)O)(3)] (12(Cu)), which are obtained under similar reaction conditions. The porosity of the series of cubic MOFs with twf-d topology reaches up to 66%. While the diameters of the spherical pores remain unaffected, adsorption measurements show that the pore volume can be fine-tuned by the substituents of the triazolyl isophthalate ligand and choice of the respective copper salt, that is, copper sulfate, selenate, or nitrate.
呈现了一组由 10 种微孔铜基金属有机骨架（MOFs）组成的同构系列，其通式为 (∞)(3)[{Cu(3)(μ(3)-OH)(X)}(4){Cu(2)(H_2O)(2)}(3)(H-R-trz-ia)(12)] (R = H, CH(3), Ph; X(2-) = SO(4)(2-), SeO(4)(2-), 2 NO(3)(2-) (1-8)) 和 (∞)(3)[{Cu(3)(μ(3)-OH)(X)}(8){Cu(2)(H_2O)(2)}(6)(H-3py-trz-ia)(24)Cu(6)]X(3) (R = 3py; X(2-) = SO(4)(2-), SeO(4)(2-) (9, 10))，以及密切相关的化合物 (∞)(3)[Cu(6)(μ(4)-O)(μ(3)-OH)(2)(H-Metrz-ia)(4)]Cu(H_2O)(6))(2)·10H_2O (11) 和 (∞)(3)[Cu(2)(H-3py-trz-ia)(2)(H_2O)(3)] (12(Cu))，这些化合物是在相似的反应条件下获得的。具有 twf-d 拓扑结构的立方 MOFs 系列的孔隙率高达 66%。虽然球形孔的直径保持不变，但吸附测量表明，通过三唑基间苯二甲酸配体的取代基和各自的铜盐（即硫酸铜、硒酸盐或硝酸盐）的选择，可以精细调整孔体积。
