Absolute Stereochemistry of Chelate Complexes Saito

Chelate Complexes, Absolute Stereochemistry of (Saito) Chirality Due to the Presence of Hydrogen Isotopes at Noncyclic 10 95... 

For many years no attempt was made to determine the absolute stereochemistry of transition metal complexes, although Kuhn (8) calculated the absolute configuration of (—)n-[Co(C204)3]3- from its anomalous optical rotatory dispersion, using classical coupled oscillator theory. He later (9) extended his theory to other tris-chelated cobalt complexes such as (+)n-[Co(en)3]3+. However, in 1955 Saito (10) showed by anomalous X-ray dispersion that Kuhn s suggested configuration for (+)n-[Co(en)3]3+ was incorrect.
