and bromodimetallates(III) of rare earth elements Cs 3 RE 2 X 9 , of which only a few have been observed in a phase diagram, were prepared and investigated by Guinier-Simon X-ray technique. Except for Cs 3 Sc 2 Br 9 (isotypic with Cs 3 Cr 2 Cl 9 ) they - for RE = Sc, Y,Ho-Lu, X = Cl as well as RE = Sc, Sm-Lu, X = Br - crystallize with the Cs 3 Tl 2 Cl 9 -type structure.
摘要 利用Guinier-Simon X射线技术制备和研究了稀土元素Cs 3 RE 2 X 9 的烯氯和溴二金属化物(III),其中只有少数在相图中观察到。除了 Cs 3 Sc 2 Br 9 (与 Cs 3 Cr 2 Cl 9 同型)它们 - 对于 RE = Sc, Y,Ho-Lu, X = Cl 以及 RE = Sc, Sm-Lu, X = Br - 结晶具有Cs 3 Tl 2 Cl 9 型结构。
