Synthesis and spectral studies on chromium(III),manganese(II),iron(III),cobalt(II),nickel(II0 and copper(II) complexes of fourteen-membered and sixteen membered tetradentate macrocyclic ligands

摘要

Complexes of Cr(III),Mn(II),Fe(III),Co(II),Ni(II) and Cu(II) with a 14-and 16-membered macrocyclic ligands have beenprepared and characterized by elemental analyses,molar conductance,magnetic moment,infrared,electronic and EPR spectral studies.All the complexes are found to have six-coordinate geometry and are of the high-spin type.
