Circular dichroism and the configuration of deprotonated tris-tartrato chromium(III) complex
Artikel i vetenskaplig tidskrift, 1978

A complex with the composition Cr(THt1̄)3 (T = RR-tartrate2−) has been characterised in solutions with excess of tartrate by circular dichroism (CD) and potentiometric data. The CD shows peaks ϵ1 - ϵr/M−1cm−1 of +4.60 at 570 nm and −0.80 at 655 nm. Together with stereochemical considerations this strongly indicates that the complex Cr(RR-TH−1)3 takes the Λ configuration. The partially protonated forms show less pronounced stereoselectivity.
