【Abstract】 One dimensional chain cobalt coordination polymer with α-Furoic acid,4,4′-bipyridine and cobalt carbonate was synthesized and characterized in the solvent mixture of water and methanol.It crystallized in a triclinic space group P（1） with a=1.138 4（4） nm,b=1.138 4（4） nm,c=1.302 9（9） nm,γ=120.0°,（V=）（1.462 3（12） nm³）,D_c=1.612 g/cm³,Z=3,F（000）=729.R₁=0.049 0,wR₂=0.143 6. The（crystal） structure shows that the cobalt（Ⅲ） atom was coordinated with two nitrogen atoms from the two 4,4-（bipys）,two oxygen atoms from two α-Furoic acid molecules and two oxygen atoms from two water molecules,forming a distorted octahedral geometry.The cyclic voltametric behavior of the complex was also studied.The results showed that it was a stable complex,and there was a quasi-reversible redox process for the complex and the complex was stabilized.更多还原
