Other Cobalt n Compounds

Other Cobalt n) Compounds. The binding of cobalt(ii) to plasma proteins has been examined. The structure of partially exchanged, fully dehydrated zeolite A has been reported. The cobalt(ii) ions were found to be in trigonal-planar environments.  

Cobalt(ni).—The optical activity associated with d-d transitions in dissymmetric cobalt(iii) complexes has been examined in terms of a model which incorporates both ligand field theory and the one-electron static-coupling theory of optical activity. Expressions have been obtained which relate the sign of the net or total d-d rotatory strength to specific stereochemical features in the ligand environment. Sector rules based on these expressions have been proposed and tested. A model for predicting the photo-reactions and quantum yields of cobalt(iii) complexes has been devised.
