Investigations on some d10 metal-ion complexes with 12-membered tellurium containing tetraazamacrocycles

Author(s): Nitu Rathee and Krishan K. Verma

A novel series 12-membered ditellura tetraazamacrocyclic complexes, [ML1Cl2], [ML2Cl2] and [ML3Cl2], where [M = Zn(II), Cd(II), Hg(II); L1, L2 and L3 = 12-membered tellurium containing tetraazamacrocyclic ligands] have been prepared via the template condensation of 1,3- diaminopropane 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, conductance measurements, infrared, electronic absorption and proton magnetic resonance spectral techniques. The spectral studies confirm the formation of 12-membered tetraazamacrocycle skeletons and their tetra dentate nature involving four nitrogen atoms. A distorted octahedral geometry has been assigned to all the metal complexes on the basis of these studies.
