One-dimensional polyoxometalate polymer constructed from V-W cluster by using asymmetrical bipyridine ligand

摘要

The asymmetrical organic molecule 2,4'-bipyridine (bpy) is explored to assemble polyoxometalate into a one-dimensional hybrid and compound [Cu~I(bpy)_2]_3[Cu~I_3(bpy)_4][V~VW~(VI)_9W~V_3O_(40)] (1) is achieved. Compound 1 represents a V-centered Keggin [V~VW~(VI)_9W~V_3O_(40)]~(6-) cluster bonded together by incorporating secondary metal coordination group of Cu-bpy. The thermogravimetric analysis of 1 has also been researched.
