摘要

A new compound, [Cu-I(bib)](2)[Cu-II(bib)(2)(beta-Mo8O26)]center dot 4H(2)O (1) (bib = 1,4-bis(1-imidazol-y1)-2,5-dimethyl benzene), has been synthesized under the hydrothermal condition and characterized by elemental analysis, TG, EDS, IR, XRD and single-crystal X-ray diffraction. Single-crystal X-ray diffraction analysis reveals that compound 1 exhibits a complicated (1D + 3D) metal-organic pseudo-rotaxane framework (MOPRF). This fashion is rare in the previous reports on pseudo-rotaxane structure, namely, one "loop" encircles two "strings" rather than a single one. Furthermore, electrochemical studies show that 1 has good electrocatalytic activity toward oxidation of biologic molecule dopamine (DA).
