| Abstract: | One new anionic Coordination Polymer, namely Co(H2O)6]2 +·Co3(bptc)2(H2O)10]2 −·3H2O (1), where H4bptc = 3,3′,5,5′-biphenyltetracarboxylate, has been synthesized hydrothermally and characterized. In compound 1, bptc4 − as tridentate ligands connect the Co2 + cations to form a 2D layer with 1D pseudo channels encapsulation of Co(H2O)6]2 + guest. In addition, their adsorption activities for organic dyes were investigated in aqueous solution. The results suggested that the anionic complex 1 show rapid and selective adsorption of cationic dyes for Neutral red, Methylene blue. |
