Abstract The review is a follow-up of a previous article (I. Haiduc, J. Coord. Chem. (2019). DOI: 10.1080/00958972.2019.1641702), which introduced structures with five-membered nitrogen heterocycles as inverse coordination centers. This review presents a panorama of organic six-membered nitrogen heterocycles acting as center cores in inverse coordination metal complexes and covers pyrazine, pyrimidine, pyridazine, triazine, tetrazine, pyridine, polypyridines, piperidine, diazabicyclooctane (DABCO) and urotropine (hexamethylenetetramine) playing such a role.

摘要 本综述是前一篇文章 (I. Haiduc, J. Coord. Chem. (2019). DOI: 10.1080/00958972.2019.1641702) 的后续文章，该文章介绍了以五元氮杂环作为逆配位中心的结构。这篇综述展示了有机六元氮杂环作为反配位金属络合物中心核的全景图，涵盖了吡嗪、嘧啶、哒嗪、三嗪、四嗪、吡啶、多吡啶、哌啶、二氮杂双环辛烷 (DABCO) 和乌洛托品 (六亚甲基四胺)职务。
