Mr. Reddy et al., SYNTHESIS, CHARACTERIZATION AND ELECTROCHEMISTRY OF UNSYMMETRICAL MACROCYCLIC COBALT(II) COMPLEXES DERIVED FROM BIS(BENZIL)ETHYLENEDIIMINE, Indian journal of chemistry. Sect. A: Inorganic, physical, theoretical & analytical, 35(8), 1996, pp. 677-680
Macrocyclic cobalt(II) complexes with varying ring sizes (12-14 member
ed) have been synthesized by using template method with bis(benzil)eth
ylenediamine precursor. These complexes have been characterized by ele
mental analyses, conductance, IR and electronic spectra. The spectral
data suggest octahedral geometry for all the complexes. Various ligand
field parameters have been calculated. The CV results suggest that th
e cobalt complexes derived from aromatic diamines are reduced at more
negative potentials.
