Abstract
AbstractThree new two‐dimensional metal‐organic frameworks (MOFs), namely [Cu3(NDIC)3 ⋅ C2H5OH ⋅ 2H2O]n (1), [Co2(NDIC)2 ⋅ 2 C3H7NO ⋅ H2O]n ⋅ nC2H5OH (2) and [(Zn3O)2(Zn(H2O)4)(NDIC)6 ⋅ C3H7NO ⋅ C2H5OH ⋅ C2H5O ⋅ 7H2O]n (3) based on the ligand 5‐norbonene‐2,3‐dicarboximide isophthalic acid (H2NDIC) have been synthesized under solvothermal condition, which have been further characterized by single crystal X‐ray diffraction analysis, powder X‐ray diffraction ( PXRD) elemental analysis, ICP, TG and FT‐IR spectroscopy. The ligand displayed distinctive coordination modes to connect mononuclear metal ion, binuclear and trinuclear metal clusters to generate different 2D layered structures in compound 1–3. Compound 1 shows KGM type network based on paddle‐wheel Cu2(COO)4 as secondary building units (SBUs). Compounds 2 and 3 have the undulating 2D (4, 4) SQL topology with the point symbol (44 ⋅ 62) based on Co2(COO)4 and Zn3(μ3‐O)(COO)4 as SBUs, respectively. The magnetic properties of compound 1–2 and the luminescent property of compound 3 and its fluorescent detection for Fe3+ has been investigated and discussed.
