稀土果糖-高氯酸及稀土-果糖-硼酸配合物的研究

Study on the Complexes of Rare Earth Fructose Perchloric Acid and Rare Earth Fructose Boric Acid

首次合成了镧（Ｌａ）、镨（Ｐｒ）、钕（Ｎｄ）、钐（Ｓｍ）、钆（Ｇｄ）的果糖－高氯酸固体配合物以及Ｌａ，Ｐｒ，Ｎｄ，Ｓｍ，Ｇｄ和Ｅｕ（铕）的硼酸－果糖配合物．利用化学分析，ＩＲ，１ＨＮＭＲ，ＵＶ和热谱等物理化学手段对这两系列共１１个配合物的组成和成键情况进行了表征，并对它们的某些物理化学性质进行了研究．结果表明：稀土－果糖－高氯酸配合物的组成为：ＲＥ３（Ｃ６Ｈ１１Ｏ６）５（ＯＨ）２（ＣｌＯ４）２３Ｈ２Ｏ（ＲＥ＝Ｌａ，Ｐｒ，Ｎｄ，Ｓｍ，Ｇｄ）；稀土－果糖－硼酸配合物的组成为：ＲＥ（Ｃ６Ｈ１２Ｏ８Ｂ）２Ｃｌ２ＣＨ３ＯＨ，（ＲＥ＝Ｌａ，Ｐｒ，Ｎｄ，Ｓｍ，Ｅｕ，Ｇｄ）．

The solid complexes of fructose perchloric acid for La, Pr, Nd, Sm and Gd, and the complexes of fructose boric acid for La, Pr, Nd,Sm, Gd and Eu have been synthesized for the first time. The compositions, bonding conditions and physicochemical properties of the eleven complexes of the above two series have been determined and characterized by chemical analyses, IR, 1H NMR, UV and thermograph. These data have indicated that the rare earth fructose perchloric acid has the composition of RE 3(C 6H 11 O 6) 5(OH) 2(ClO 4) 2·3H 2O(RE=La,Pr,Nd, Sm, Gd), and the rare earth fructose boric acid has the composition of RE(C 6H 12 O 8B) 2Cl·2CH 3OH(RE=La,Pr,Nd,Sm, Eu,Gd),respectively.
