Structure and Electrochemical Properties of a one Dimensional Chain Cobalt Coordination Polymer Co(α-Furoic acid)2(4,4'-bipy)2(H2O)2
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 P1 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),Dc=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.
