英文摘要：

A novel one-dimensional zinc（Ⅱ） coordination polymer [Zn（acac）2（4,4＇-bipy）]n was solvothermally synthesized and characterized by IR, elemental analysis, thermal analysis, ^1H NMR, and X-ray diffraction methods. The complex crystallized in monoclinic system, space group P2（1）/c with a=1.1366（10）nm,b=1.4914（14）nm,c=1.5534（10）nm,β=132.00（4）°,V=1.957（3）nm^3,Z=4. It was confirmed that the Zn（acac）2 and 4,4＇-bipy formed a one-dimension linear structure with molecular ratio of 1：1. The result of TG analysis showed that the title complex was stable under 197 ℃. The distribution of charges and the composition of frontier molecular orbits provided a good testimony for the coordination condition in the crystal structure.
