钴、镍、铜与磷酰化丙氨酸固体配合物的制备及光谱研究

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

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。

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.
