Absolute configuration tacn

Cn the basis of the above results, it is assumed that the earlier eluted enantiomers, whose major CD peaks have negative sign, have the same arrangement with respect to the glycinate and an unidentate (CN-, NO-, NH., NCS-, H20, OH-, N -, or Cl-). An X-ray analysis has been carried out for (-)[Co (gly) (NH. ) -(tacn)]lyHS), and its absolute configuration has been determined as shown in Figure 18 (32).
