Synthesis, crystal structure and properties of a chiral 2D Zn(II) coordination polymer with helical chains

Abstract

A chiral two-dimensional (2D) coordination polymer {[Zn(cmmb)(1,4-bbi)]·H2O}n (1) has been synthesized by a hydrothermal reaction of Zn(NO3)2 ·6H2O with 4-(carboxymethoxy)-2-methylbenzoic acid (H2cmmb) and 1,1′-(1,4-butanediyl)bis(imidazole) (1,4-bbi). It has been characterized by elemental analysis, X-ray crystallography, IR spectroscopy and thermogravimetry, and also by its fluorescence properties. The metal-organic layer of the complex is held together with its neighbors via C-H...O hydrogen bonds to give rise to a chiral three-dimensional supramolecular network. © 2013 Verlag der Zeitschrift für Naturforschung, Tübingen.
