Two-dimensional organic–inorganic hybrid materials based on β-octamolybdate units linked by [{Cu(imi)(phen)}2Cl]3+ and K+ bridges

A new organic–inorganic hybrid material, formulated as K[{Cu(imi)(phen)}2Cl][Mo8O26] (1) (imi = imidazole, phen = 1,10-phenanthroline), has been synthesized under hydrothermal conditions and structurally characterized by elemental analysis, IR spectra, thermal analysis and single-crystal X-ray diffraction. Compound 1 consisted of image cluster, dinuclear copper complex image and K+ ion, in which the β-octaolybdate building block is linked by the coordination bridge image and the inorganic bridge K+ into a 2D organic-inorganic framework through M–O–M′ bonds (M = Mo, M′ = Cu, K). The electrochemical behavior of compound 1 has been studied in detail based on a solid bulk-modified carbon paste electrode of compound 1 (1-CPE).
