Abstract

Abstract: A comparative study on the exo-coordination-based networking of 15-membered O2 S2 -macrocycle isomers (L 1 andL 2 ) induced by interdonor distances is reported. In copper(I) bromide complexation, the isomerL 1 incorporating a shorter sulfur-to-sulfur separation yielded a discrete dimer complex [( μ -Cu2 Br2 )(L 1 )2 ] (1 ) in which two macrocycles are bridged by a Cu2 Br2 square cluster. While, the reaction of copper(I) bromide with the isomerL 2 incorporating a longer sulfur-to-sulfur separation afforded a double-stranded one-dimensional (1D) coordination polymer {[( μ 4 -Cu2 Br2 )(L 2 )2 ]·CH2 Cl2 } n (2 ) as a kinetic product which converted to [( μ 4 -Cu2 Br2 )(L 2 )2 ] n (3 ) with different 1D connectivity pattern as a thermodynamic product. The results indicate as examples of programmed self-assembly that the proposed interdonor distances and the ligand isomerism play decisive roles cooperatively in the topologies of the supramolecular products via different coordination modes.
