钴,镍,铜与磷酰化丙氨酸固体配合物的制备及光谱研究

研究了Ｃｕ（Ｉ）、Ｃｏ（Ｉ）、Ｎｉ（Ｉ）的Ｎ－磷酰化丙氨酸（ＤＩＰＰＡｌａ）固体配合物的制备，并通过元素分析、红外光谱、ＸＰＳ、电子光谱以及热分析等手段对配合物的结构进行了表征．研究表明，Ｃｕ与ＤＩＰＰＡｌａ的羧基形成四配位结构，而Ｃｏ、Ｎｉ则与羧基及水形成六配位结构．热分析实验表明，三种配合物的分解温度相近，但Ｃｕ配合物的分解活化能更高

Syntheses and Spectral Study of the Solid Complexes of DIPP Ala With Cu(II), Co(II) and Ni(II)

The solid complexes of DIPP Ala with Cu(II), Co(II) and Ni(II) are synthesized in this work. The complexes are characterized by elemental analyses, FT IR, electronic absorption spectra, X ray photoelectron spectroscopy and thermal decomposition analyses. The results indicate that the copper binds to carboxylic groups of DIPP Ala and forms a tetracoordinated structure, but the cobalt and nickel complexes coordinate with carboxylic groups and water to form a hexacoordinated structure. All complexes are decomposed in the similar temperature range, but copper complex has higher activation energy in decomposition.
