N4 coordination sphere about the MnIII ion. The MnIII complexes of pyrrolecarboxamide ligands are square pyramidal with a fifth Cl atom, whereas analogous complexes of indolecarboxamide ligands are essentially square planar. Electrochemical studies reveal highly negative MnIII/II and moderately positive MnIV/III redox potentials. In situ generated Mn4+ species of the pyrrolecarboxamide ligands were

Few nickel(II) and copper(II) complexes have been prepared with three new indolecarboxamide ligands (H4L3, H4L4 and H4L5) offering two Namide and two Nindole donor sites to the metal center. The ligands carry electron-donating (–CH3); –H; and electron-withdrawing (–Cl) substituents on the phenylene backbone to evaluate their effect on the structure and redox properties of the metal complexes. One of the
