A new series of 10-membered tellurium containing tetraazamacrocyclic complexes, [ML1Cl2], [ML2Cl2] and [ML3Cl2], where [M=Zn(II), Cd(II), Hg(II); L1, L2and L3=10-membered tellurium containing tetraazamacrocyclic ligands] have been prepared via the template condensation of ethylenediamine and diaryltellurium dichlorides, R2TeCl2, (R=p-hydroxyphenyl, 3-methyl-4-hydroxyphenyl,p-methoxyphenyl) in the presence of metal chlorides. These complexes have been characterized by elemental analyses,

IR and PMR spectra confirm the formation of 10-membered tetraazamacrocycle skeleton and their tetradentate nature. An octahedral geometry has been assigned to all the metal complexes on the basis of various physicochemical studies.
