Description
Summary:A new organic-inorganic hetero-coordination polymer with three different kinds of ligands [Co(4,4′-bpy)(NCS)2(py)2]n is synthesized in the extremely mild condition. The X-ray diffraction reveals that the title polymer has a highly tactic three-dimensional cagelike supramolecular structure. Although the coordination bond makes it a one-dimension chain, the hydrogen bond plays an important role in the formation of 3-D supramolecular frameworks. The determination of magnetic properties has been carried out, and shows that it behaves weak antiferromagnetic property with J4,4′ -bpy = -3.8cm-1.
