Ligand Modulation on the Various Structures of Three Zinc(II)-Based Coordination Polymers for Antibiotics Degradation

“…The uncoordinated oxygen atom of the carboxylate group in 1,4-bdc is involved in the formation of the C–H⋯O (2.423 Å) interaction between the carboxylate group and the pyridyl molecule; similarly, the formation of the C–H⋯O (2.365 Å) interaction between the imidazole group and the carboxylate group stabilizes the framework. As a result, CPs3 is a 3D supramolecular polymer composed of hydrogen bonds and stacking interactions [ 52 ] ( Figure 3 d).…”

Structures and luminescence properties of one co‐edge bi‐rhomboid [Zn6] based 1D stair‐stepping polymer and one quasi‐linear tetra‐nuclear [Cd4] cluster with orotic acid

“…The bond length of ZnÀ N is 2.091(2) Å and the bond lengths of ZnÀ O fall in the range of 1.922(2)-2.251(2) Å, which are comparable with those for the reported orotate-based Zn(II) polymers. [15,22,25] Every HOA 2À ligand bridges three Zn(II) ions (two Zn1 and one Zn2) with a coordination mode of μ 3 -η O 2 :η N 1 :η O 1 (Figure 1b).…”

“…Specifically, the research of luminescent MOCCs has attracted much attention for their promising potential in the areas of fluorescent sensors, bioprobes and hybrid organic–inorganic light‐emitting diodes (LEDs) [10–13] . However, the design and synthesis of the MOCCs with excellent luminescent properties are still a great challenge because the resulting structures and performances are susceptible to many factors such as the nature of organic ligands and metal centers, temperature, pH values and solvents [14–18] …”

“…The d 10 metal ions of Zn(II) and Cd(II) with closed‐shell electronic configuration were often used to prepare luminescent MOCCs which could display a variety of coordination numbers and avoid the attenuation or quenching of ligand‐based emissions which was usually observed in the paramagnetic 3d systems [15,19,20] . In addition, a proper selection of organic ligands is also very important to build such luminescent materials.…”
