Synthesis, structure, adsorption and electrochemical properties of the new two-dimensional cobalt coordination polymer based on bifunctional ligand
A novel two-dimensional coordination polymer {[Co(Htia)2(C2H5OH)2]·H2O}n(1) (H2tia = 5-(1H-1,2,4-triazol-1-yl)isophthalic acid, C10N3O4H7) was successfully synthesized by a solvothermal method using H2tia containing –COOH and –N bifunctional groups as ligands and transition metal Co as the central ion. 1 was analyzed by XRD, IR, UV and TG. Single-crystal X-ray diffraction analysis shows that Co2+ ions in 1 are the hexagonal distorted octahedral geometry. Neighboring Co2+ ions form a two-dimensional grid using the Htia ligand as the rigid skeleton. The adjacent 2D layers interact through hydrogen bonds to build a three-dimensional supramolecular crystalline material. Based on the laminar structure of 1, we investigated the adsorption capacity of 1 on two cationic dyes, crystalline violet and Janus green B. The results show that 1 has a certain adsorption capacity and the maximum adsorption amount of the dyes can reach as high as 56 and 176 mg g−1, respectively. The electrochemical experiment shows that 1 has good electrocatalytic activity in the electrolyte solution of 0.01 M KOH not only for the oxidation of H2O2, but also for the oxidation of ascorbic acid.
期刊介绍：
Transition Metal Chemistry is an international journal designed to deal with all aspects of the subject embodied in the title: the preparation of transition metal-based molecular compounds of all kinds (including complexes of the Group 12 elements), their structural, physical, kinetic, catalytic and biological properties, their use in chemical synthesis as well as their application in the widest context, their role in naturally occurring systems etc.
Manuscripts submitted to the journal should be of broad appeal to the readership and for this reason, papers which are confined to more specialised studies such as the measurement of solution phase equilibria or thermal decomposition studies, or papers which include extensive material on f-block elements, or papers dealing with non-molecular materials, will not normally be considered for publication. Work describing new ligands or coordination geometries must provide sufficient evidence for the confident assignment of structural formulae; this will usually take the form of one or more X-ray crystal structures.
