  甲醇取代的卤化镧的结构表征

  摘要：

  使用甲醇（MeOH）进行了卤化镧[LaX（3）]衍生物的醇溶化作为降低LaBr（3）闪烁体生产温度的一种手段的首次研究。最初，通过在室温下简单地将1溶解在MeOH中，研究了{[La（micro-Br）（H（2）O）（7）]（Br）（2）}（2）（1）的脱水。分离出混合的溶剂化物单体[La（H（2）O）（7）（MeOH）（2）]（Br）（3）（2）化合物，其中La金属中心通过与两种其他的MeOH溶剂，但必须将内球Br转移到外球。为了尝试将1的甲醇中的反应混合物在CaH（2）上干燥，分离了[Ca（MeOH）（6）]（Br）（2）（3）的晶体。在回流温度下将化合物1溶解在MeOH中，导致分离出异常结构，该结构被确定为盐衍生物{[LaBr（2.75）* 5.25（MeOH）]（+ 0.25）[LaBr（3.25）* 4.75（MeOH）]（- 0.25）}（4）。最终，通过将干燥的LaBr（3）溶

  Examination of the LnCl3/RLi alkylation system for organic synthesis using yttrium as a probe including the X-ray crystal structure of Li2Y8Cl18O4(THF)12

  摘要：

  The LnCl(3)/RLi reagent system commonly used with Ln = Ce for organic alkylation reactions has been studied with Ln = Y to make Y-89 nucleus (I = 1/2) in NMR analyses. The 'YCl3' obtained by the current literature methods of dehydrating LnCl(3)(H2O)(x) reagents in the LnCl(3)/RLi system contains water by elemental analysis, by reactivity with LiCH2SiMe3 and LiMe, and by X-ray analysis of recrystallized material which proved to be [YCl2(H2O)(6)]Cl. The complexity of the intermediates that may be present in these systems when reagents are not rigorously purified is shown by the structure of Li2Y8Cl18O4(THF)(12), which was isolated from a YCl3/LiCH2SiMe3 reaction. The complex contains a tetracapped tetrahedron of yttrium atoms with two outlying lithium atoms all of which are connected by four mu(4)-O, fourteen mu(2)-Cl, and two mu(3)-Cl atoms. Each lithium and each capping yttrium are ligated by two THF groups. (C) 1997 Elsevier Science S.A.

  The reactions of [YCl2(H2O)6]Cl with 18-crown-6 in aliphatic alcohol solutions afford the complexes [Y(H2O)3(18-crown-6)]Cl3·1.25H2O (1) and [Y(H2O)8]Cl3·(18-crown-6)·4H2O (2), in which the inner coordination sphere of yttrium consists of nine and eight oxygen atoms, respectively. The inner-sphere transformations of complexes 1 and 2 under conditions of solid-state thermolysis were investigated. After the removal of coordinated water molecules from compound 1, the complex undergoes a structural transformation at temperatures above 180 °C, resulting in that two chloride anions enter into the coordination sphere of yttrium. For compound 2, a double exothermic effect is observed in the temperature range of 160–300 °C due to the formation of a certain new structural species containing chloride ions and 18-crown-6 in the inner coordination sphere.
