are limited to metal complexes with a perimidine scaffold that are in a narrow range of between six and eight d electrons (on metals from groups 8–10). This manuscript showcases the synthesis of four d10 metal complexes with a perimidine scaffold. The gold and silver complexes have a linear geometry, while the copper and platinum complexes are three-coordinated. All complexes were characterized by
N-杂环卡宾 (NHC) 是有机金属化学的重要辅助配体,虽然已经合成了许多变体,但迄今为止最常见的是基于五元环的,如咪唑或苯并咪唑。与建立在五元环上的 NHC 复合物通常是共轭的不同,六元环 NHC 变体的探索集中在非共轭版本上,例如N , N '-二氨基碳烯。共轭六元环 NHC 的报告仅限于具有在 6 到 8 个 d 电子之间的窄范围内的 perimidine 支架的金属配合物(在第 8-10 族的金属上)。这份手稿展示了 4 d 10的合成金属配合物与periimidine 支架。金和银配合物具有线性几何形状,而铜和铂配合物是三配位的。所有配合物均通过单晶 X 射线晶体学、多核 NMR 和其他光谱方法进行表征。
