In the June issue of Chem, Chilton, Liddle, and colleagues reported the synthesis and characterization of uranium(IV)-oxo and -imido complexes that exhibit anomalously high low-temperature magnetic moments as a result of nearly doubly degenerate spin-orbit ground states. Traditional crystal-field arguments prove paramount in the elucidation of the electronic configuration of the uranium(IV) molecules.

通过磁性发现 U(IV) 复合物固有的伪双基态

在Chem 6 月刊中， Chilton、Liddle 及其同事报道了铀 (IV)-氧代和-亚胺配合物的合成和表征，这些配合物由于自旋轨道基态几乎双重退化而表现出异常高的低温磁矩. 传统的晶体场论证在阐明铀 (IV) 分子的电子构型方面是最重要的。
