Construction of nine non-covalently-bonded zinc(II) and cadmium(II) supramolecules containing the mixed-ligands of 3,5-dimethylpyrazole and carboxylates: Their synthesis and characterization

Coordination-Driven Heterochiral Self-Assembly: Construction of Cd(II) Coordination Polymers with Sorption Behaviors for Iodine and Dyes

“…The Cd–N and Cd–O bond lengths vary in the range of 2.304(3)–2.393(3) Å. All of the bond angles around the Cd­(II) ions are similar to other octahedral Cd­(II) complexes. , In the extended coordination environment, each Cd­(II) center is connected by four ligands with a Cd­(II)···Cd­(II) separation of 9.819 Å (Figure b). This rare coordination mode of the ligands with Cd­(II) ions leads to the formation of a 3D framework coordination polymer, which can be simplified as a (4,4) coordination network (Figure c).…”

“…This 2D structure further self-assembles via weak hydrogen bonds to form a 3D supramolecular framework (Figure 3d). 53,54 In the extended coordination environment, each Cd(II) center is connected by four ligands with a Cd(II)•••Cd(II) separation of 9.819 Å (Figure 4b). This rare coordination mode of the ligands with Cd(II) ions leads to the formation of a 3D framework coordination polymer, which can be simplified as a (4,4) coordination network (Figure 4c).…”

Synthesis, characterization, POM analyses and biological evaluation of n-[(2-methoxy-5- nitrophenyl)]-4-oxo-4-[oxy] butenamide based zinc(II) carboxylate complexes

“…The carboxylate complexes of zinc(II) with ligands of nitrogen or oxygen donors have been proved highly significant in biochemical aspects, i.e. biological and chemical point of view in current era [6,7].…”
