Abstract

A series of 20-memebered macro-cyclic metal (II) complexes have been synthesized by a macro-cyclic ligand, ie 1, 5, 11, 15-tetraaza-6, 10, 16, 20-tetraoxo-8, 18-dithia-cyclocosane, it was prepared by the condensation reaction of 1, 3-diaminopropane with thiodiglycolic acid. The bonding and stereochemistry of the complexes have been characterized by elemental analysis, magnetic moment, molar conductance, mass, 1H NMR, IR, electronic and EPR ...
