Abstract Studies of the synthesis of solid state nitrides using a Na flux are reviewed. The role and effect of Na is to solubilize polyatomic species containing nitrogen, and to lower the crystal growth temperature below the decomposition temperature of the obtained product(s). Many new ternary and quaternary nitrides have been synthesized in single crystal forms with sizes at least large enough (or larger) than is needed for structure analysis by X-ray diffraction. Isolated and extended anionic groups typically containing N and Si, Ge, Ga, and/or some transition metal elements are typical. These are usually surrounded by alkaline-earth atoms and are the most common of such nitrides. Compounds composed of nitridometallate anions and Zintl polyanions are also obtained. The structural features of each of these compounds are described.

氮化物的钠熔剂合成

摘要 综述了使用钠熔剂合成固态氮化物的研究。Na的作用和作用是溶解含氮的多原子物质,并将晶体生长温度降低到所得产物的分解温度以下。许多新的三元和四元氮化物已经以单晶形式合成,其尺寸至少足够(或更大)比通过 X 射线衍射进行结构分析所需的尺寸要大。通常包含 N 和 Si、Ge、Ga 和/或一些过渡金属元素的孤立的和扩展的阴离子基团是典型的。它们通常被碱土原子包围,是最常见的此类氮化物。还获得了由氮化金属阴离子和 Zintl 聚阴离子组成的化合物。描述了这些化合物中的每一个的结构特征。
