Design of Low Symmetry Complexes

From the preceeding chapters it can be seen that the preparative studies of today vely on various techniques of chromatography and optical resolution. It is also important to make a good choice of the conditions to be used in this sense the reactions should be designed for the object. 

Recent applications of the ligand field theory to the transition metal complexes give logical interpretations of d-d absorption spectra, and the theoretical treatments help to predict band positions in the absorption spectra of complexes. On the other hand, today low-symmetry complexes are synthesized which contain ligands of more than three kinds. Their spectral data are expected to further develop theoretical fields of spectroscopy. 

This chapter deals mainly with the complexes which are preparable from the green solution of tricarbonatocobaltat ni) by diamminedicarbonato-type complexes, and whose absorption or CD spectra are characteristic for low synunetry.
