Optically active co-ordination compounds. Part IV. Aquations of resolved halogeno-complexes

Abstract

In the aquation of a resolved complex of the type cis-[Co en₂XY]ⁿ⁺ where Y is a halide ion and X a unidentate ligand such as Cl^–, NH₃, NO₂^–, and NCS^–, successive optical rotatory dispersion spectra pass through common points ([ϕ],λ). The significance of such common points is discussed, and the results used in conjunction with mechanistic information, to show that optical configuration retained during aquation of halogeno-complexes.
