Abstract
Cobalt(
III) complexes of tridentate ligands containing oxime-diamine and oxime-amino acid donor sets have been prepared, both by reduction of the related imine complexes. Many of the complexes have been characterized by X-ray crystallographic techniques. The photochemistry of these complexes has been studied. The oxime-diamine systems are rather unreactive, undergoing slow isomerization before decomposition. The oxime-amino acid systems appear to undergo decarboxylation reactions. Photolyses of tetrachlorozincate salts of some of the complexes result in binuclear species in which a trichlorozinc moiety is bound to the cobalt species through an oxime oxygen atom.
