  • Abstract

    The synthesis and characterisation of cobalt(III) chelates of 3-nitroformazans have been described. These chelates have been characterized as tris chelates on the basis of elemental analysis, IR and 1H NMR studies. These studies reveal that the coordination of the cobalt(III) to the ligands occurs through the nitrogen atoms 1 and 5 of the formazyl group and that the NO2 group of the ligand does not take part in coordination. The structure of these chelates contains three symmetric six membered CN4Co rings.
