镍的配合物在材料、催化、光学性质、磁学性质等方面具有重要的研究意义。芳香羧酸配合物的合成与结构研究一直是人们关注的热点课题之一．芳香羧酸与金属离子构筑的配合物在材料（如催化、光学、信息存贮）、药物、分子电化学、生物化学、生物制药等许多领域中表现出了潜在的应用价值。

One dimensional chain nickel（1） coordination polymer has been synthesized with 2,4,6-trimethylbenzoic acid, 4,4′-bipyridine and nickel perchlorate anhydrous, and characterized in the solvent mixture of water and methyl-alcohol. Crystal data for this complex： monoclinic, space group C2/c, a=2.154 7（7） nm, b=1.131 9（2） nm, c=1.655 7（8） nm,β=129.66（3）^o, V=3.108 7（19） nm^3, Dc=1.370 g.cm^-3, Z=4, F（000）=1 360, final GooF=1.042, R1= 0.034 4, wR2=0.078 7. The crystal structure shows that the nickel ion is coordinated with two nitrogen atoms of two 4,4′-bipyridine molecules and four oxygen atoms from two 2,4,6-trimethylbenzoic acid molecules and two water molecules, respectively, forming a distorted octahedral coordination geometry. The cyclic voltametric behavior of the complex is also reported. CCDC： 649415.
