  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

For the smallest three lanthanides, Tm, Yb, and Lu, the metal center is 12 coordinate because one of the DMADB groups chelates to the metal center by means of only three B–H···Ln bridges. The structures of the base-free Ln(H3BNMe2BH3)3 complexes are highly dependent on the size of the lanthanide ions: as the ionic radius decreases, the coordination

  Abstract In this review we describe a variety of rare earth metal boride halides and boride carbide halides. In boride halides boron atoms occur either as discrete atoms octahedrally coordinated by rare earth metal atoms or as chains of interconnected B 4 rhomboids in rods of fused metal atom bisphenoids. Characteristic building units in boride carbide halides are quasi-molecular B–C, C–B–C, C–B–B–C
