摘要

本文报道了三种新型铕碳二亚胺氯化物的固态合成和结构：Eu4(NCN)3Cl3=Eu(3+)Eu3(2+)(NCN)3Cl3 (1), LiEu2(NCN)Cl3(2)和Na2Eu14(NCN)3Cl24(3)。1是继Eu4F5(NCN)2之后第二个混合价稀土碳二亚胺的例子。2属于一类与璧辉土族有关的混合碳二亚胺化合物。3是第一个含na的稀土碳二亚胺。稀土碳二亚胺的合成得益于使用不同的碱碳二亚胺直接反应生成单个化合物。报道了1-3的高产率合成、晶体结构和3的光致发光性质。

Cationic Control of the Formation of Europium Carbodiimide Chlorides

The solid-state syntheses and the structures of three new europium carbodiimide chlorides are reported: Eu₄(NCN)₃Cl₃=Eu⁽³⁺⁾Eu₃⁽²⁺⁾(NCN)₃Cl₃ (1), LiEu₂(NCN)Cl₃ (2) and Na₂Eu₁₄(NCN)₃Cl₂₄ (3). 1 is the second example of mixed-valent rare-earth carbodiimide after Eu₄F₅(NCN)₂. 2 belongs to a group of mixed carbodiimide compounds related to the Bideauxite group. 3 being the first Na-containing rare-earth carbodiimide. Syntheses in the field of rare-earth carbodiimides benefit from the usage of different alkali carbodiimides to direct reaction pathway into individual compounds. High-yield syntheses of 1–3, their crystal structures, and the photoluminescence properties of 3 are reported.
