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

Using an exo ligand containing a pyridine unit as a monodentate coordinatio n 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 se lf-assembly conditions; a single-crystal X-ray study revealed that in the c rystalline phase the 1-D networks are packed in a centrosymmetric fashion.
