Three oxidation states (+2, +3, +4) of an octahedral nickel center were stabilized in a newly prepared RhNiRh trinuclear complex, [Ni{Rh(apt) } ] (apt=3- aminopropanethiolate), in which the nickel center was bound by six thiolato donors sourced from two redox-inert fac-[Rh (apt) ] octahedral units. The three oxidation states of the octahedral nickel center were fully characterized by single-crystal X-ray crystallography, as well as spectroscopic, electrochemical, and magnetic measurements; all three were interconvertible, and the conversion was accompanied by changes in color, magnetism, and Jahn-Teller distortion.
一种新型制备的 RhNiRh 三核配合物[Ni{Rh(apt) } ]（apt=3-氨基丙硫醇）中稳定存在镍原子的三种价态（+2、+3、+4），其中镍中心由两个氧化还原惰性的 fac-[Rh(apt) ] 八面体单元提供的六个硫醇配体所键合。通过单晶 X 射线晶体学、光谱、电化学和磁性测量对八面体镍中心的三种价态进行了全面表征；这三种价态是相互转化的，并且转化伴随着颜色、磁性和 Jahn-Teller 变形的变化。
