Benzoate substituents effects on the structure of Zn(II) complexes and 1D 4,4′-bipyridine derived coordination polymers

Amide-Driven Secondary Building Unit Structural Transformations between Zn(II) Coordination Polymers

“…42−44 These differences generally result in changes in the coordination number, 45 geometry, 40 or dimensionality 46 the SBUs are relatively scarce, 32,47−49 and to the best of our knowledge, no examples of CPs presenting multiple alterations of its initial SBU by DRSTs can be found in the literature. In this scenario, our group has been working during the last years on the synthesis of CPs based on 4,4′-bipyridine 50 and the preparation of Zn(II) and Cd(II) complexes bearing αacetamidocinnamic acid (HACA) and different pyridine derivatives. 51−54 These studies resulted in the obtention of a series of ACA-based compounds with different nuclearities encompassing monomeric, dimeric, trimeric, and even polymeric compounds extended through the ACA ligand.…”

“…In this scenario, our group has been working during the last years on the synthesis of CPs based on 4,4′-bipyridine and the preparation of Zn­(II) and Cd­(II) complexes bearing α-acetamidocinnamic acid (HACA) and different pyridine derivatives. − These studies resulted in the obtention of a series of ACA-based compounds with different nuclearities encompassing monomeric, dimeric, trimeric, and even polymeric compounds extended through the ACA ligand. From them, the obtention of trimeric compounds with pinwheel arrays has especially attracted our attention, studying the effect of the intramolecular N–H···O CO synthon between vicinal ACA ligands, which plays an important role in the stabilization of the SBU .…”

Zn(II) and Cd(II) monomer, dimer and polymer compounds coordinated by benzoic acid and 4-acetylpyridine: Synthesis and crystal structures

“…Unlike these previous results, the reaction between ZnO and 3,5-HDHB yielded a coordination polymer [Zn(μ-3,5-DHB)2(H2O)2]n, which in presence of isonicotinamide (Isn), 4-acetylpyridine (4-Acpy) and 3-methylpyrazole (3-Mepz) generated monomeric complexes [18]. The role of 4,4′-bipyridine (4,4′-bpy) as linker via its reaction against Zn(MeCO2)2, 3,5-HDHB or 3,5-H(MeO)2Bz was also studied [19].…”

A Zinc(II) Coordination Polymer Based on a Chain of {Zn2O7} Bitetrahedra Bridged by 3‐Methoxybenzoates

“…[5][6][7] In the last two decades several carboxylates of Zn(II) or the higher congener Cd(II) have been studied by many research groups. [8][9][10][11][12][13][14][15][16][17][18][19][20] These studies have resulted in the characterization of several zinc coordination polymers of varying dimensionalities (1D or 2D or 3D) which exhibit interesting structures and luminescene properties. [8][9][10][11][12][13][14][15][16][17] The structures of several dinuclear Zn(II) carboxylates with bridging hydroxo ligand are archived in the Cambridge structural database (CSD).…”

[21] An analysis of more than forty structures retrieved from the CSD (Table S1) reveals that a majority of these compounds are prepared hydrothermally using hydrated zinc(II) salts like zinc acetate, [22][23] zinc nitrate, [24][25] zinc chloride [26][27] etc.…”
