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.
