We have demonstrated a single‐crystal‐to‐single‐crystal (SCSC) transformation from a two‐dimensional noninterpenetrated layer to a microporous three‐dimensional fourfold interpenetrated MOF. The centrosymmetric [Co2(μ2‐OH)(EIBA)3]n (SNUT‐25) transforms into a microporous [Co(EIBA)2]n (SNUT‐26), which is triggered by the reaction time with DMF that acts as a structure‐directing agent (HEIBA = 4‐(2‐ethyl‐1H‐imidazol‐1‐yl)benzoic acid; DMF = N,N′‐dimethylformamide). Despite the distinct structure and coordination arrangements of SNUT‐25 in contrast to SNUT‐26, both Co‐MOFs were synthesized using the same ligand. Fascinatingly, upon introducing a specific quantity of DMF combined with a negligible proportion of nitric acid, SNUT‐25 will progressively and completely transform into SNUT‐26. Under the synergistic induction of solvent molecules and temperature, SNUT‐25 changed from the original two‐dimensional layered structure to the three‐dimensional pore structure of SNUT‐26. In addition, SNUT‐25 and SNUT‐26 are efficient photocatalysts for the degradation of organic dye methyl blue (MB) under visible light irradiation. Surprisingly, the degradation rates of both SNUT‐25 and SNUT‐26 can reach over 96%. In addition, SNUT‐25 and SNUT‐26 also exhibited high electrocatalytic oxygen evolution reaction.

Two new Cu(II) complexes namely, Cu(PDC)2.H2O (1) and {[Cu(1,3-BIP)(PDC)(NO3)]·2H2O}n (2) (1,3-BIP = 1,3-di(1H-imidazol-1-yl)propane; HPDC = 5-methyl-4-oxo-1-phenyl-1,4-dihydropyridazine-3-carboxylic acid) have been sythesized and characterized by single crystal x-ray ananlyses, thermogravietr -ic techniques. The single-crystal x-ray diffraction reveals that complex 1 shows a zero-dimensional structure, which is further reinforced through strong intermolecular hydrogen bonding to form a 3D suparmolecular framework. Complex 2 exhibits a one-dimensional ring structure, which are further linked by intermolecular hydrogen bonding to form a 3D supermolecular architecture. The optimized geometric bond lengths and bond angles of complex 1 obtained by using density functional theory (DFT) have been compared with X-ray diffraction values. In addition, the antimicrobial activity of the complex 1 and the photocatalytic activity of the complex 2 were also investigated. [ABSTRACT FROM AUTHOR]
