Syntheses and crystal structures of two Keggin- based supramolecular compounds by using different organonitrogen ligands
Abstract：Two new Keggin - based organic - inorganic hybrid compounds, （ H3/4 Me2bpy） 4[ PW12 040 ] ·3 H20 （1） and （H6/5bbi） 25 [ PMo1204o ] · H20 （2） （ Me2bpy = 5,5＇ - methyl - 2,2＇ - bipyridine, bbi = 1,1＇ - （1,4 -butanediyl）bis（imidazole） ）, have been synthesized by hydrothermal methods, and characterized byIR 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, R =0. 0892, a~R2 =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）,a= 93.60（3）,β=94.71（3）, T= 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 oroDerties are studied by cvclic voltammetrv.
