| 摘 要： | 本文合成了阴离子为氯离子和高氯酸根的镧的甘氨酸配合物Ｌａ（Ｇｌｙ）３（ＣｌＯ４）３·Ｈ２Ｏ和Ｌａ（Ｇｌｙ）３Ｃｌ３·３Ｈ２Ｏ，测定了配合物的红外光谱，并作了比较研究。结果表明：配合物因阴离子的不同而形成二种不同的结构，二者都为一维长链结构，但甘氨酸的配位方式不同；在Ｌａ（Ｇｌｙ）３Ｃｌ３·３Ｈ２Ｏ中，有两分子水参与了配位，而Ｌａ（Ｇｌｙ）３（ＣｌＯ４）３Ｈ２Ｏ中则有一分子的高氯酸根参与了配位。

| Abstract: | Two lanthanum-glycine amino acid complexes, La(Gly)3 (ClO4)3 x H2O and La(Gly)3Cl3 x 3H2O, were synthesized with different anion ions. The infrared spectra of two complexes were characterized. The results show that the two complexes have different structures with different anion ions and the water molecules exit with different status in the two complexes. The results also indicate that one of the perchlorate ions is involved in the coordination in La(Gly)a(ClO4)3 x H2O. |
