Two-Dimensional Square-Grid versus One-Dimensional Double-Stranded Networks:  Counterion Regulation of the Formation of Macrocycle-Based Copper(I) Coordination Frameworks

Abstract

A two-dimensional square-grid-shaped coordination polymer incorporating the dithiaoxa macrocycle (1), [Cu(1)CN] n (2), has been prepared by a self-assembly process involving the interaction of 1 with CuCN; the parallel reaction of 1 with CuI afforded the one-dimensional double-stranded coordination polymer [Cu(1)I] n (3).

Crystal‐to‐Crystal Transformation between Three CuI Coordination Polymers and Structural Evidence for Luminescence Thermochromism

“…In addition, a number of Cu I coordination polymers based on copper(I) iodide and bidentate ligands have been synthesized by self‐assembly reactions 6. The structures of self‐assembled coordination polymers depend on a delicate balance between alternative conformations of the organic ligands and on the nature of the metals and anions,7 as well as the solvent employed 5c. 8 Our interest in Cu I coordination chemistry is mainly focused on thioether ligands 6.…”

Dithioether ligands containing a 2,6-disubstituted pyridine linker with two thioether-heterocycle arms

“…These dithioether compounds can also be used as antiviral compounds (Joseph-McCarthy et al, 2001;Tsang et al, 2001). Furthermore, compounds bearing S and N donor atoms tend to form a great variety of structurally interesting supramolecular entities, in particular with group 11 metals (Peng et al, 2006;Han et al, 2005;Amoore et al, 2005;Li et al, 2004;Park et al 2005). Since the flexible backbone of these dithioethers allows great structural diversity, we first investigated the Cambridge Structural Database (CSD, Version 5.30;Allen, 2002) in order to understand the influence of the chemical nature of the outer rings on the structural and conformational properties of the dithioether ligands.…”

Hydrothermal synthesis and crystal structure of a novel cyanide-bridged double helical copper(I) coordination polymer [Cu3(CN)3(phen)]

“…The cyanide group is capable of functioning as a straight connector to yield a linear -Cu-CN-chain in copper(I) cyanide. Copper(I) ion is in favor of trigonal or tetrahedral coordination in the presence of cyanide and pyridyl groups gives the possibility of promoting the formation of frameworks because of the strong coordinating nature of these ligands and their ability to act as connector between different copper centers [14]. The synthetic strategies of copper(I) cyanide coordination polymers are either incorporating organic amine ligand into copper(I) cyanide framework or using Cu(II) ion as the precursor and K 3 [Fe(CN) 6 ] as cyanide source which affords cyanide-bridged Cu(I) complexes under hydrothermal condition.…”
