One-dimensional chain copper(Ⅱ) coordination polymer has been synthesized and characterized in the solvent mixture of water and alcohol with o-acetamidobenzoic acid,4,4’-bipyridine and copper perchlorate.It is of tetragonal,space group P41212 with a=1.57756(10),b= 1.57756(10),c=2.1438(3)nm,V=5.3352(8) nm3,Dc=1.524 g/cm3,Z=4,F(000)=2536,R= 0.0479 and wR=0.0979.The crystal structure shows two coordination modes.The copper(1) is coordinated with two nitrogen atoms of one 4,4’-bipyridine molecule and two oxygen atoms from two o-acetamidobenzoic acid molecules,forming a distorted tetrahedral coordination geometry;the copper(2) is coordinated with two nitrogen atoms of one 4,4’-bipyridine molecule,four oxygen atoms from two o-acetamidobenzoic acid molecules and two water molecules,generating a distorted octahedral coordination geometry.The result of TG analysis shows that the title complex is stable below 180.0 ℃.

The crystal structure shows two coordination modes. The copper (1) is coordinated with two nitrogen atoms of one 4,4’-bipyridine molecule and two oxygen atoms from two o-acetamidobenzoic acid molecules, forming a distorted tetrahedral coordination geometry ; the copper (2) is coordinated with two nitrogen atoms of one 4,4’-bipyridine molecule, four oxygen atoms from two o-acetamidobenzoic acid molecules and two water molecules, generating a distorted octahedral coordination geometry. that the title complex is stable below 180.0 ℃.
