Abstract The eight possible mixed chloro-iodo and bromo-iodo complexes (including each three pairs of geometrical isomers) of osmium(IV) were separated by electrophoresis, and the detailed absorption spectra measured of acidic aqueous solutions. The bands in the near infra-red are due to intra-sub-shell transitions and the rest are electron transfer bands. The detailed assignment of symmetry types
摘要通过电泳分离了八种可能的mixed(Ⅳ)的
氯碘和
溴碘混合配合物(包括三对几何异构体),并测定了酸性
水溶液的详细吸收光谱。近红外中的谱带是由于子壳内跃迁而引起的,其余的是电子转移谱带。如果同时考虑到光学电负性的差异,
配体-
配体排斥的影响以及在
溴化物和
碘化物中的强相对论效应,则应该有可能详细分配激发能级的对称类型。目前只能在较小的部分进行确定的标识。但是,结果也有助于更好地理解六
碘配合物。
