One dimensional chain Zinc(II) coordination polymer [Zn(4,4′-bipy)- (o-ABA)2·(H2O)2n has been synthesized and in the solvent mixture of water and alcohol with o-acetamidobenzoic acid, 4,4'-bipyridine and zinc Perchlorate anhydrous. The crystal of the title polymer belongs to tetragonal space group P4 3212 with a=1.605 27(6) nm, 6=1.605 27(6) nm, c=2.108 96(15) nm; L=5.4346(5) nm3, Dc=1.501 g·cm -3, Z=8, F(000)=2 544, R1=0.030 1, wR2=0.067 7. The crystal structure shows that the zinc ion is coordinated with two nitrogen atoms of one 4,4′-bip...
