Reversible desorption and absorption of water in a zinc-based coordination polymer nanostructure

Abstract

A zinc-based coordination polymer [Zn(μ2-3-Clb)2·H2O]n (1), (3-HClb = 3-chloro benzoic acid), has been synthesized and structurally characterized by single crystal X-ray crystallography. It composed from one-dimensional zigzag chains but secondary hydrogen bonding interaction, extended its structure and two-dimensional supramolecular network was formed. Compound 1 nanostructure was synthesized by sonochemical procedure. Reversible desorption and adsorption of water in this zinc coordination polymer were studied by IR spectroscopy, thermo gravimetric and differential thermal analyses (TG-DTA), X-ray powder diffraction (XRD) and scanning electron microscopy (SEM).
