Two POM-tuned hybrids containing tripodal star-like ligand copper complexes, [CuII3(H2O)5(tib)2(P2Mo5O23)]·2H2O (1) and [CuI2(Htib)2(PMo11VIMoVO40)]·H2O (2) (tib = 1,3,5-tris(1-imidazolyl)benzene), have been hydrothermally synthesized. In compound 1, a 2D wave-like layer is constructed from concave belts bridged by P2Mo5 polyoxoanions in a “hand-in-hand” mode, extending to a 3D supramolecular framework via hydrogen bonding interactions. Compound 2 shows a 1D ladder-like chain formed by [Cu(tib)] chains acting as two sides of the ladder and PMo12 anions acting as middle rails, resulting in a 3D supramolecular structure through hydrogen bonding interactions. The steric hindrance of polyoxoanions, the valence states of copper ions and the coordination modes of tib ligands co-affect together the final structures of title compounds. The electrochemical properties of compounds 1 and 2 are investigated.
Two polyoxomolybdate-tuned hybrids modified by tripodal star-like ligand copper complexes are successfully synthesized. The steric hindrance of polyoxoanions, the valence states of copper ions and the linking modes of tib ligands co-affect the final structure of compounds. The electrochemical properties of the title compounds are also investigated.Figure optionsDownload as PowerPoint slideHighlights
