Abstract: | Complexes of Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Pd(II), Pt(II), Ru(III) and Ir(III) with a sixteen-membered 1,5:11,15-dimetheno-2,4,10,12-tetramethyl-1,5,9,13]-tetraazahexadeca-1,3,5,6,10,11,13,15,16,20-decene macrocyclic ligand have been synthesized. These complexes are characterized by magnetic moment, infrared, electronic, EPR and mössbauer spectral studies. All of complexes were found to have six-coordinated octahedral geometry and are of the high spin type except for the Pd(II) and Pt(II) complexes which are four coordinate, square planar and diamagnetic. |
