金属身份，d-电子数和配位几何形状对金属-配体多重键（MLMB）的电子结构的影响是一个积极探索的领域。虽然高氧化态的Cr亚氨基化合物已被广泛研究，但关于低价Cr亚氨基化合物或氧化还原异构体的相互转化的报道很少。在这里，我们报告的合成和表征的二吡咯烷合铬亚胺络合物的氧化态范围从铬-III到铬-V的家庭，展示的影响，弱场dipyrromethene支架上的电子结构和配位几何这些铬酰亚胺。
The effect of metal identity, d-electron count, and coordination geometry on the electronic structure of a metal-ligand multiple bond (MLMB) is an area of active exploration. Although high oxidation state Cr imidos have been extensively studied, very few reports on low-valent Cr imidos or the interconversion of redox isomers exist. Herein, we report the synthesis and characterization of a family of dipyrrinato Cr imido complexes in oxidation states ranging from Cr-III to Cr-V, showcasing the influence of the weak-field dipyrromethene scaffold on the electronic structure and coordination geometries of these Cr imides.
