Design, synthesis and structural investigation of a 1-D directional coordination network based on the self-assembly of an unsymmetrical mono-tridentate ligand and cobalt cation

Abstract

Using an exo ligand containing a pyridine unit as a monodentate coordination site and a PyS₂ moiety as a tridentate coordination pole, a directional 1-D coordination network has been obtained in the presence of CoCl₂ under self-assembly conditions; a single-crystal X-ray study revealed that in the crystalline phase the 1-D networks are packed in a centrosymmetric fashion.
