在水溶液中合成了高氯酸铒与甘氨酸和丙氨酸混配配合物［Ｅｒ＿２（Ｇｌｙ）＿４）（Ａｌａ）＿２（Ｈ＿２Ｏ）＿４］（ＣｌＯ＿４）＿６·３Ｈ＿２Ｏ，测定了其单晶结构。晶体属三斜晶系，Ｐ１空间群。晶胞参数为ａ＝１．１２８６（５）ｎｍ，ｂ＝１２４４ｂ（２）ｎｍ，ｃ＝０．９４２３（２）ｎｍ，ａ＝７７．６３（２）°，β＝７５２７（２）°，γ＝６４．４５（２）°，Ｖ＝１．１４６６（５）ｎｍ￣３Ｚ＝１，Ｄ＿ｃ＝２．１５４ｇ／ｃｍ￣３。该配合物为链状分子，甘氨酸和丙氨酸的羧基均以桥式与相邻的两个铒离子配位，铒的配位数为８，形成四方反棱柱型配位多面体。 Er 2 (Gly) _4) (Ala) _2 (H_2O) _4] (ClO_4) _6 · 3H_2O complexes were synthesized from aqueous solutions of erbium perchlorate, glycine and alanine, and their single crystal structures were determined. Crystal is a triclinic, P1 space group. The cell parameters are a = 1.1286 (5) nm, b = 1244b (2) nm, c = 0.9423 (2) nm, a = 77.63 γ = 64.45 (2) °, V = 1.1466 (5) nm~3Z = 1, D_c = 2.154g / cm~3. The complex is a chain molecule. The glycine and alanine carboxyl groups are bridged to two adjacent erbium ions, and the coordination number of erbium is 8, forming a tetragonal anti-prismatic coordination polyhedron.
