二茂铁基取代酰腙的一些过渡金属配合物

Some Transition Metal Complexes of Ferrocenyl Substituted Hydrazones

本文制备了两个金属有机配位体,肉桂醛二茂铁基甲酰腙(HL^1)和二[(1-肉桂酰肼基乙基)环戊二烯基]铁(H_2L^2)及它们与一些过渡金属的配合物:ML_2~1[M=Cu(Ⅱ)],ML^2[M=Ca(Ⅱ)和Zn(Ⅱ)],M(HL^1)2Cl_2[M=Cd(Ⅱ),Co(Ⅱ)和Ni(Ⅱ)],M(H_2L^2)Cl_2[M=Mn(Ⅱ),Zn(Ⅱ),Co(Ⅱ)和Cd(Ⅱ)].这两个配位体以烯醇式与M(OAc)_2·nH_2O中心离子配位,与MCl_2·nH_2O则以酮式配位.

Two organometallic ligands, cinnamaldehyde ferrocenecarbonylhydrazone (HL^1) and bis [(1-cinnamoylhydrazonoethyl) cyclopentadienyl] iron (H_2L^2) have been prepared. Some of transition metal complexes: ML_2~1[M=Cu(Ⅱ)], ML^2[M=Cu(Ⅱ) and Zn(Ⅱ)], M(HL^1)_2C1_2[M=Cd(Ⅱ), Co(Ⅱ), and Ni(Ⅱ)], M(H_2L^2)Cl_2[M=Mn(Ⅱ), Zn (Ⅱ), Co (Ⅱ), and Cd (Ⅱ) ] were obtained by the reaction of HL^1 and H_2L^2 with relevant metal (Ⅱ) acetates and chlorides, respectively. These ligands coordinate in the enolic form with M(OAc)_2·nH_2O and in the keto form with MCl_2·nH_2O.
