A series of cobalt polynitrides has been discovered by using laser-heated diamond anvil cells under high pressure that demonstrate an increasing degree of nitrogen polymerization with increasing pressure. Synthesis under high pressure and high temperature, coupled with single-crystal synchrotron X-ray diffraction and micro-Raman imaging spectroscopy, offers significant advantages in elucidating the crystal structures of these nitrides along with the prospect of recovering of these materials under ambient conditions.

多氮化钴的高压合成：揭示有趣的晶体结构和氮化行为

通过在高压下使用激光加热金刚石砧池发现了一系列多氮化钴，这些多氮化钴显示出氮聚合程度随着压力的增加而增加。高压高温下的合成，加上单晶同步加速器 X 射线衍射和显微拉曼成像光谱，在阐明这些氮化物的晶体结构以及在环境条件下回收这些材料的前景方面具有显着的优势。更多信息请参阅 H. Chen、A. F. Goncharov 及其同事的研究文章 (DOI: 10.1002/chem.202400536)。
