Synthesis, Structure and Electrochemical Property of a New Three-Dimensional Inorganic–Organic Vanadate Coordination Polymer [Cu2(bbi)2(V4O12)] · 4H2O (bbi = 1,1-(1,4-butanediyl)bis(imidazole))

Abstract

A new inorganic–organic vanadate coordination polymer [Cu2(bbi)2(V4O12)] · 4H2O (bbi = 1,1-(1,4-butanediyl)bis(imidazole)) (1) has been synthesized under hydrothermal condition and characterized by elemental analyses, IR spectra and single crystal X-ray diffraction. Structure analysis revealed that the three-dimensional structure of compound 1 is constructed from two-dimensional [Cu(bbi)2]2+ layers linked through {V4O12}4− building blocks. Compound 1 represents the first example of metal-organic frameworks with non-interpenetrated five-connected topological network (46·64) based on Cu(II) as nodes, bbi and {V4O12}4− as mixed spacers. The electrochemical behavior of 1 modified carbon paste electrode (1-CPE) in 1M H2SO4 aqueous solution has been studied.
