| 摘要: [Mx(FeCO2)yLz]型配合物可在THF中通N2条件下由FeCO2H和MX2·nH2O(X=Cl-和Ac-)经长时间反应制得.IR和1HNMR谱表明Cu(Ⅲ)、Co(Ⅲ)属螯环配合物,Cd(Ⅱ)属四面体型配合物,Pb(Ⅱ)属线型化合物.M(Ⅱ)离子位于配合物中心.CV表明M(Ⅱ)呈多价态变化,受配体及敖合效应影响Fe(Ⅲ)⇔Fe(Ⅱ)和M(Ⅱ)⇔M(0)Ep/2下降,M(Ⅱ)还原力上升.M(Ⅱ)⇔M(0)Ep/2随M(Ⅱ)aq.性质呈现律性变化. |

| Abstract: The complexes of this type(Mx(FeCO2)yLz)were prepared(M=Cu(Ⅱ),Co(Ⅱ),Cd(Ⅱ),Ph(Ⅱ);L=ThF,Cl-).They are formed by FeCO2H and MX2·nH2O reaction in the THF, at long time, under the N2.The IR and 1HNMR indieate that the complexes of Cu(Ⅱ),Co(Ⅱ)belong to three cyclical chelata, complex of Cd(Ⅱ)belongs to tetrahcdard,but the compound of Ph(Ⅱ)is linear. The M(Ⅱ)is on the crystrallgraphic symmetry center.The CV indicates that Fo(Ⅲ)⇔Fe(Ⅱ)and M(Ⅱ)⇔(0)Ep/2 is fall and M(Ⅱ)reducible is rise.Because of the effeet of between M(Ⅱ)and Fe(Ⅱ)and chelate.The change of value M(Ⅱ)⇔(o)Ep/2 are regularly occording to the charters of M(Ⅱ)aq. |
