“…in which the structural details of a series of Ag + complexes of substituted imidazoles were discussed. Weak intermolecular interactions (hydrogen bonding and π–π interactions) between imidazole rings play an important role in constructing 2D assemblies from 1D chains. − Therefore, the 2D morphology of the nanoribbons of Ag-Benz could be due to the connection between a series of parallel 1D chains linked via intermolecular interactions …”

The synthesis of nanostructures with tunable antibacterial properties using green solvents at room temperature is of environmental interest, and antibacterial nanomaterials are used in the fabrication of biofouling-resistant membranes for water purification and wastewater treatment. In this study, we investigate the effect of organic ligands on the antibacterial and structural properties of silver-based metal−azolate frameworks (Ag-MAFs). Three new Ag-MAFs were synthesized with silver, as the metal center, and imidazole-based linkers having different chemistries via a facile and environmentally friendly method conducted at room temperature. The coordination of silver ions with the linkers resulted in the formation of Ag-imidazole, Ag-2 methylimidazole, and Ag-benzimidazole complexes with octahedral, hexagonal nanosheet, and nanoribbon morphologies, respectively. The Ag-MAFs exhibited excellent antibacterial activity (up to 95% die-off of bacteria at a short exposure time of 3 h) in colloidal forms against both Gram-negative Escherichia coli (E. coli) and Gram-positive Bacillus subtilis (B. subtilis) because of synergetic effects of silver and the imidazole-based linkers. Ag-2 methylimidazole showed the highest antibacterial activity, owing to its high silver concentration and special nanocrystal structure that provides better contact with bacteria. This work indicates that the antibacterial activity of Ag-MAF nanostructures can be tailored by changing the organic linker, allowing for creating nanostructures with desired biocidal properties.

“…Remarkably, herein we report the synthesis of two new 3 d -4 f heterometallic coordination polymers (HCP) based on Ce III and two different 3 d cations, Co II or Cu II , by using a single organic linker, the bifunctional ligand 1 H -imidazole-4,5-dicarboxilyc acid (H 3 IDC). H 3 IDC has proven to be an excellent ligand to construct coordination polymers with intricate and beautiful structures, using different metals cations such as from n s block, − 3 d , − and 4 d transition cations ,, and with lanthanide cations. , The versatility of this ligand also relies on the multiple anionic species that can be generated: H 2 IDC – , HIDC 2– , and IDC 3– , which not only allows the balance of charges of the cations but also gives multiple coordination sites with different coordination capabilities. Nevertheless, 3 d -4 f HCPs using this ligand as organic linker are still scarce.…”

In the present work, we report the synthesis and characterization of two new heterometallic coordination polymers based on CeIII and containing CoII or CuII cations, assembled by the bifunctional ligand 1H-imidazole-4,5-dicarboxylic acid, [Ce(H2O)2(HIDC)Co(IDC)]·H2O CoCe and [Ce(H2O)2(H2IDC)Cu(H2O)(IDC)Cu0.2(H1.6IDC)] CuCe. Compound CoCe was obtained under one pot hydrothermal synthesis, while CuCe was synthesized by a step-by-step synthesis using the metalloligand [Cu(H2IDC)2(H2O)2] Cu1, as precursor. From a structural point of view, CoCe presents an intrincated 3D structure, in which alternating Λ-Δ chiral CoII chains can be observed, which are assembled by discrete CeIII fragments, giving rise to the 3D structure. Meanwhile, CuCe presents a structure formed by [Cu2Ce2] heterometallic chains, partially assembled by CuII cations in a 2D structure. Magnetic properties reveal that both CoCe and CuCe present a global antiferromagnetic behavior, dominated by the interaction between CoII-CoII or CuII-CuII entities connected by μ2-κN,O-κO′′′,N′ bridges, belonging to H3IDC anionic derivatives. Moreover, a weak ferromagnetic phenomenon was found in compound CoCe, corroborated by hysteresis loops and ac magnetization.
