a clear identification and characterization of preferred conformations and configurations at an atomic resolution. Our study has evidenced some key features of the overall 3D structure of pma-Zn and pma-Co complexes which shapes are set by the geometry of the metallacycle, the configuration of the sp3 nitrogen atom, the equatorial position of the benzyl side arm as well as the preferred spatial arrangement
摘要介绍了吡啶基甲基胺(pma)-ZnBr2和-CoBr2配合物的制备。使用结合了先进NMR的方法(例如纯位移梯度编码的选择性重聚焦(PS-GSERF)和常规的NOESY实验,DFT计算和X射线分析),可以获得溶液和固态的准确结构信息。所开发的方法已允许以原子分辨率清楚地鉴定和表征优选的构象和构型。我们的研究证明了pma-Zn和pma-Co配合物的整体3D结构的一些关键特征,其形状由金属环的几何形状,sp3氮原子的结构,
