Preparation and electrochemical sensing performances toward bromate and Cr(VI) of two γ-octamolybdate-based complexes decorated by in situ transformation ligand
Two octamolybdate-based complexes formulated by [M2(H2O)4(γ-Mo8O26)(HDIBA)2]·H2O [M = Co (1), Zn (2), DIBA = 3,5-di(1H-imidazol-1-yl)benzoic acid], were synthesized successfully by using hydrothermal method in the presence of 3,5-di(1H-imidazol-1-yl) benzonitrile (DICN) as initial ligand. The DIBA ligand was generated in situ from the hydrolysis of DICN ligand. The γ-octamolybdate polyoxoanion was decorated by two DIBA ligands relying on Mo−O covalent bonds between the carboxyl oxygen atom of DIBA ligand and Mo atom of polyoxoanion. The transition metal centers joined in pairs these modified γ-octamolybdate polyoxoanions into a 1D chain, which were further aggregated to result in a 2D layer. The investigations on the electrochemical performances indicated that the two complexes displayed electrocatalytic and electrochemical sensing activities for bromate and Cr(VI), which provide potential electrode materials in preparing the electrochemical sensors and electrocatalysts.
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.
