“…Rigid ligands with a high degree of directionality were originally used as linkers in order to obtain specific crystal motifs [18]. However, the employment of more flexible ligands in the development of coordination polymers has lately been explored by numerous research groups [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. The flexibility arises from the rotation of single bonds in carbon chains [22], allowing for various conformations that can result in distinct final structures [24].…”

In the present work, novel polymeric copper(II) coordination compounds, namely [Cu2(cpida)(H2O)4][Cu(cpida)]·3H2O (1) (cpida3− = 2-(carboxyphenyl)iminodiacetate anion) and Na[Cu(cpida)] (3), were synthesized and characterized using infrared spectroscopy, thermogravimetric analysis, elemental analysis, and single-crystal X-ray diffraction. Compound 1 was obtained by slowly evaporating an aqueous solution of H3cpida, copper(II) sulfate, and NaOH at room temperature. The structural characterization revealed that 1 is an ionic entity formed by the [Cu(cpida)]− anion and the [Cu2(cpida)(H2O)4]+ cation, both of polymeric 1D structure. Compound 3 was prepared under similar conditions from copper perchlorate and crystallized via acetone diffusion. It is a coordination polymer formed by the [Cu(cpida)]− units, and the sodium cation is present in the structure, counterbalancing the anion charge. Depending on the crystallization conditions, it was possible to obtain other solvation forms of these structures. Starting from the conditions of compound 1, via the diffusion of ethanol, [Cu2(cpida)(H2O)4][Cu(cpida)]·H2O·1/2EtOH (2) was precipitated, while a hydrate form of compound 3 with the formula Na[Cu(cpida)]·2H2O (4) was obtained via methanol diffusion.

“…The type of ligand and the configuration of the complexes play crucial roles in the catalytic performance of copper complexes. Aminopolycarboxylic ligands, such as iminodiacetic acid, are not only strong chelate ligands but also feature the coordination diversity to form coordination polymers in different synthetic conditions [20,21]. Imidazole ligands are also widely used in the syntheses of metal complexes due to their coordination abilities [22].…”

The mixed-ligand copper(II) iminodiacetates [Cu(ida)(2-mim)(H2O)2]·H2O (1), [Cu(ida)(2-mim)2]·2H2O (2), [Cu(ida)(2-mim)(H2O)]n·4.5nH2O (3), and [Cu2(ida)2(2-mim)2]n·nH2O (4) (H2ida = iminodiacetic acid, 2-mim = 2-methylimidazole) were obtained from neutral or alkaline solutions at different temperatures. The novel complex 4 contains very small holes with diameters of 2.9 Å, which can adsorb O2 selectively and reversibly between 1.89 to 29.90 bars, compared with the different gases of N2, H2, CO2, and CH4. This complex is stable up to 150 °C based on thermal analyses and XRD patterns. The four complexes show catalytic activities that facilitate the conversion of cyclohexane to cyclohexanol and cyclohexanone with hydrogen peroxide in a solution. The total conversion is 31% for 4.

In the present study we have reported fabrication and structural determination of 3D microspheres/custard‐apples shaped mesoporous CuII chelate polymer (CP) from a 1D chelating ligand for enhanced an antioxidant and antibacterial activities. The CP was fabricated from a novel chelating ligand suberoyl bis(2‐ethoxybenzamide) (sbebz) with copper salt by condensation, while sbebz was synthesized from 2‐ethoxybenzamide and suberoyl chloride, and was structurally authenticated by 1HNMR, 13CNMR, FT‐IR, Mass spectroscopy, XRD, and SEM. As‐fabricated CP was characterized by XRD, FT‐IR, EDS, UV‐DRS, XPS, Raman, SEM, TEM, AFM, BET, and TG for authentication of its structure, shape, size, chemical state, composition, purity, surface behavior, porosity, and thermal stability. SEM revealed nearly monodispersity in microspheres, while TEM rendered average particles sizes of 10–47 nm. AFM supported nearly homogenized nature of microspheres, while BET rendered a mesoporosity. Further, antioxidant property of CP was examined by using α, α‐diphenyl‐β‐picrylhydrazyl (DPPH) in ethanolic/methanolic solvents, while ascorbic acid was used as a standard medium. Furthermore, the antibacterial activity of both materials was tested against human pathogenic bacteria viz. gram +Ve (Staphylococcus aureus, and Bacillus substilis), and gram –Ve (Escherichia coli and Klebsiella pneumoniae). Moreover, molecular docking of sbebz was performed using both genetic (GA) and non‐genetic (Non‐GA) algorithm techniques, where result demonstrated an excellent docking energy.
