“…Among various aspects of forming interpenetration in the structure of MOFs, the nature of the ligand, particularly the length and flexibility of the ligand, has to be considered as one of the important parameters. The flexibility of the ligand sometimes play an important role in the generation of interpenetration in the structure. , It is prevalent for mixed ligand MOFs that the combination of polycarboxylates and N-donor ligands is the most efficient way to produce the desired assembly. , Among the polycarboxylates both aromatic and aliphatic multidentate polycarboxylates have been chosen frequently as the building blocks in the construction of CPs due to their diverse coordination modes. − Whereas in the context of N, N donor linkers like bispyridyl, bisimidazole, , bistriazole, − etc. have been utilized most extensively to link up metal ions in MOF.…”

Interpenetration or catenation is well explored in the network structure of metal organic frameworks, but these kinds of networks were considered as not usable for normal applications of conventional open metal−organic frameworks (MOFs). Recently, flexibility in such networks was found to be an important factor to introduce functionality in the structures of MOFs, and also, the understanding of the factors that control interpenetration also become important. To date, there is no obvious root that has been found to have an interpenetrated network with successive flexibility. In search of such types of networks and to explore the avenue of understanding of growing interpenetration in a framework, six new metal−organic frameworks (MOFs) of Cu(II), Cd(II), and Zn(II) have been synthesized from three flexible dicarboxylates and two rigid dicarboxylates along with 2-methyl-1-(4-(2-methyl-1H-imidazole-1-yl)butyl)-1H-imidazole, as a coligand. All of these synthesized complexes have been characterized by single crystal and powder X-ray diffraction and were further characterized by elemental analysis, infrared spectroscopy (IR), and thermogravimetric analysis (TGA). N 2 , CO 2 , H 2 , and CH 4 sorption studies were also done for all the MOFs, and the characteristic surface adsorptions were found in all cases. Here, from the studies of all these complexes, a common observation is found: flexible dicarboxylates give a noninterpenetrated framework whereas rigid linkers give an interpenetrated framework.

Utilizing semirigid lactic acid derivatives (R)‐H2CBA and (S)‐H2CBA as chiral ligands, two pair of homochiral coordination polymers formulated as [Zn((R)‐CBA)(1,4‐DIB)]·H2O (1‐D), [Zn((S)‐CBA)(1,4‐DIB)]·H2O (1‐L), [Co((R)‐CBA)(1,4‐DIB)]·H2O (2‐D) and [Co((S)‐CBA)(1,4‐DIB)]·H2O (2‐L) were prepared under solvothermal reaction condition. Single X‐ray diffraction study reveals that all the complexes are comprised of three kinds of helical chains, which are constructed by corresponding metal ions, CBA2– ligands, and/or 1,4‐DIB ligands. Moreover, some physical characteristics, such as PXRD, thermal stabilities, solid‐state circular dichroism (CD), luminescent and magnetic properties are also investigated.
