Abstract

A polymetallic assembly containing mutually coordinated highly reactive UO2+ groups was isolated in the presence of dibenzoylmethanate. NMR studies showed unambiguously the presence of the cation-cation complex in pyridine solution while more polar solvents lead to the disruption of the UO2+/UO2+ interaction and increased stability.

摘要

在二苯甲酰甲烷存在的情况下，分离出了一种含有相互配位的高活性UO2+基团的多金属组装体。核磁共振研究明确显示，在吡啶溶液中存在阳离子-阳离子络合物，而极性更强的溶剂会导致UO2+/UO2+相互作用的破坏并提高稳定性。
