Abstract:Two new Keggin-based organic-inorganic hybrid compounds,(H3/4Me2bpy)4·3H2O(1) and(H6/5bbi)2.5·H2O(2)(Me2bpy = 5,5′-methyl-2,2′-bipyridine,bbi = 1,1′-(1,4-butanediyl)bis(imidazole)),have been synthesized by hydrothermal methods,and characterized by IR spectra,elemental analyses and single crystal X-ray diffraction.Compound 1 crystallizes in the monoclinic system,space group P21/n,a=13.229(3),b=23.449(5),c=13.720(3),β=118.61(3),V=3736.6(13),Z=2,R1=0.0892,ωR2=0.1548.Compound 2 crystallizes in the triclinic system,space group P 1,a=12.021(2),b=12.131(2),c=20.441(4),α= 93.60(3),β=94.71(3),γ= 103.21(3),V=2881.8(10),Z=2,R1=0.1064,R2=0.2102.These two title compounds are made into carbon paste electrode(CPE) and their electrochemical properties are studied by cyclic voltammetry.
