Özet

© 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.Four mixed-ligand coordination polymers, namely, [Zn(μ-3,3′-Cl2abdc)(μ-4,4′-azobpy)]n (1), [Zn(μ-4,4′-Cl2abdc)(μ-3,3′-azobpy)0.5(H2O)]n (2), [Zn2(μ-4,4′-Cl2abdc)(μ4-4,4′-Cl2abdc)0.5(μ-OH)(μ-4,4′-azobpy)]n (3) and {[Zn(H2O)4(μ-4,4′-azobpy)](4,4’-Cl2abdc)}n (4) (Cl2abdc: dichloroazobenzenedicarboxylate and azobpy: azobispyridine) were synthesized with azo-group containing positional isomer anionic and neutral ligands in the presence of Zn(II) ion and characterized by elemental analysis, IR spectroscopy, single-crystal X-ray diffraction. X-ray results showed that the compounds displayed structural diversity depending on disposition of donor groups on ligands and solvent. Compounds 1 and 2 exhibited two-fold and five-fold interpenetrated 2D → 2D structures, respectively, with the interchanging of positional isomer anionic and neutral ligands. Five-fold polycatenated 2D → 3D structure was observed with the selection of 4,4′-Cl2abdc and 4,4′-azobpy in 3. Although same ligands were used in the synthesis of 4 like compound 3, 1D structure of 4 was obtained with the use of DMF:water mixture and zinc nitrate. 4,4′-Cl2abdc acted as a counter-ion in 4. Furthermore, topologic, thermal, optical and photoluminescence spectra of the compounds were studied in detail.
