1, 1'-Di(N-salicyloylhydrazonoethyl) ferrocene and Its Coordination Compounds with Transition Metals

本文合成了1,1'-二(N-水杨酰腙乙基)二茂铁及其过渡金属配合物,ML·nH_2O[M=Mn(Ⅱ)、Co(Ⅱ)、Ni(Ⅱ)、Cu(Ⅱ)、Zn(Ⅱ)和Cd(Ⅱ)],并用元素分析、UV、IR、~1H NMR、TG-DTA和摩尔电导进行了表征.配体以烯醇式通过亚胺基氮原子和酰胺基氧负离子与金属离子配位,按摩尔比1:1结合.Ni(Ⅱ)配合物有一分子DMF配位.大部分配合物都比配体热稳定性高.

1, 1'-Di(N-salicyloylhydrazonoethyl) ferrocene and its coordination compounds with transition metals, ML·nH_2O[M=Mn(Ⅱ)、Co(Ⅱ)、Cu(Ⅱ)\Cd(Ⅱ)、 Zn(II) and Ni (Ⅱ)] are synthesized in this paper, and characterized by their elemental analysis、 UV-Vis, IR、~1H NMR, TG-DTA and molar conductance. The ligand coordinates metals through azomethine nitrogen atom and amide oxygen atom in enol form, Ni (Ⅱ) coordination compound contains a molecular DMF.In all coordination compounds ligand reacts with metal in 1:1 ratio and these coordination compounds are weak electralytes in DMF. Most coordination compounds are more thermostable than the Ligand.
