PHOTOCHEMISTRY OF FE(III), FE(IV), RU(III), MO(VI), AND NI(IV) DITHIOCARBAMATE COMPLEXES

Experimental results on the photochemical transformations and structur e of some Fe(III), Fe(IV), Ru(IV), Mo(IV) dithiocarbamate complexes ha ve been considered. Attention is paid to the photochemistry of the Ni( IV) dithiocarbamate complexes. The solutions of these complexes show h igh photochemical activity even in the red spectral range, which is ve ry unusual for photochemical systems. Moreover, these solutions are ph otochromic systems. Using laser flash photolysis, it has been shown th at some phototransformation steps occur inside the coordination sphere of the nickel ion. The reverse dark reactions are bimolecular process es. (C) 1997 Elsevier Science S.A.
