Abstract The synthesis of a new Schiff base macrocyclic ligand 4,5:13,14-dibenzo-9-methyl-3,15-dioxa-20-thia-7,11-diazabicyclo [15.2.1] eicosa-1(19),6,11,17-tetraene and its five transition metal complexes [ML] Cl2(M=Cu(), Ni(), Cd(), Hg(), Zn()) are reported. All compounds are characterized by elemental analysis,IR ,UV-Vis,1HNMR, MS and molar conductance measurements. Their probable structures were conjectured. The results show that oxygen and nitrogen atoms from ligand are coordinated to the metal ion.
