Synthesis and characterization of some divalent transition metal complexes with tellurium containing 10-membered tetraazamacrocyclic ligands

ABSTRACT :

A new series of 10-membered tellurium containing tetraazamacrocyclic complexes, [ML1Cl2], [ML2Cl2] and [ML3Cl2], where [M = Mn(II), Co(II), Cu(II); L1 , L2 and L3 = 10-membered tellurium containing tetraazamacrocyclic ligands] have been prepared via the template condensation of 1,2-diaminoethane and diaryltellurium dichlorides, R2TeCl2, (R = phydroxyphenyl, 3-methyl-4-hydroxyphenyl, p-methoxyphenyl) in the presence of metal chlorides. These complexes have been characterized by elemental analyses, conductivity, magnetic susceptibility measurements, infrared, electronic absorption and proton magnetic resonance spectra. An octahedral geometry has been assigned to all the metal complexes. Keywords: tellurium containing, tetraazamacrocycles, diaryltellurium dichlorides, 1,2- diaminoethane, template condensation, metal complexes.
