| 摘 要： | 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 J(4,4'-bpy) = -3.8 cm-1.

| Abstract: | 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 J(4,4' -bpy) = -3.8 cm-1. |
