A Cu-MOF ( [Cu24(mip)24(dabco)6(H2O)12] (2), (where H2mip = 5-methylisophthalic acid; dabco = 1,4-diazabicyclo[2.2.2.]octane) was prepared via conventional one-pot solvothermal reaction using Cu(II)(NO3)2 and H2mip as building blocks for the cuboctahedral MOP, [(Cu2)12(mip)24(S)24] (where S is ligated solvent molecule), and dabco as a linker between the MOPs. Cu-MOF 2 is isostructural to the reported Zn-MOF, [Zn4(mip)4(dabco)(H2O)2] (1), of a ubt net topology with 5-connected [Zn2(COO)4(Ndabco)S] (where, S is a ligated solvent molecule) cluster as a secondary building unit (SBU)). The structure of 2 was confirmed by powder X-ray diffraction (PXRD). 2 activated via vacuum-drying at ambient temperature shows type I N2 sorption isotherms having three different sizes of micropores. The microporous 2 could be converted to a series of new micro/meso-biporous MOFs with different distributions of micro/meso-bipores simply controlling the activation temperature. The mesoporosity generation via the partial elimination of dabco linker between the MOPs was confirmed using PXRD, N2 sorption and the pore size analysis.
