八面体镍中心的三个氧化态（+2、+3、+4）在新制备的 RhNiRh 三核配合物 [Ni{Rh(apt)(3)}(2)](n+)（apt = 3-氨基丙硫醇）中稳定，其中镍中心由来自两个氧化还原惰性面[Rh-III(apt)(3)]八面体单元的六个硫醇供体结合。通过单晶 X 射线晶体学以及光谱、电化学和磁测量充分表征了八面体镍中心的三种氧化态；这三者都是可以相互转换的，并且转换伴随着颜色、磁性和杨-泰勒畸变的变化。
Three oxidation states (+2, +3, +4) of an octahedral nickel center were stabilized in a newly prepared RhNiRh trinuclear complex, [Ni{Rh(apt)(3)}(2)](n+) (apt = 3-aminopropanethiolate), in which the nickel center was bound by six thiolato donors sourced from two redox-inert fac[Rh-III(apt)(3)] 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.
