A new cadmium(ii) coordination polymer with 1,4-cyclohexanedicarboxylate acid and phenanthroline derivate: Synthesis and crystal structure

Abstract

A new Cd(ii) coordination polymers, formulated as [Cd(1,4-chdc)(L)] n (1) (L = 1-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol ligands and 1,4-H2chdc = 1,4-cyclohexanedicarboxylate acid), were successfully synthesized by using L ligand and 1,4-H2chdc acid under hydrothermal conditions and characterized by single crystal X-ray elemental analyses, diffraction, and IR spectroscopy. Each Cd(ii) atom is a distorted pentagonal bipyramidal geometry connecting the deprotonated 1,4-chdc anion to form a 2D layer, and a 2D layer is formed into a 3D supramolecular structure by the π–π stacking interactions between neighboring layers.

N-Ligands mediated Co(Ⅱ) coordination polymer incorporating 5-hydroxyisophthalic acid: Syntheses, structures, and theoretical calculations

“…On the one hand, di-and polycarboxylates with flexible aliphatic backbones are expected to adopt various conformational freedoms [19,21]. In addition, due to their coordination modalities, carboxylates are also anticipated to have a significant role in mediating molecular-molecular interaction, electron transport, magnetic exchange channels and biological uses [22]. For example, the V-shaped aromatic dicarboxylate, 5-hydroxyisophthalic acid ligand (H2hip), as a multidentate O-donor ligand was used to coordinate and self-assemble into a 3D supramolecular structure with Cd(II) metal and nitrogencontaining ligands in 2021 [23].…”
