Synthesis, Characterization and Antimicrobial Studies of Nitrogen-Sulphur Donor Tellurium Containing Macrocyclic Complexes of NiII, PdII and PtII


Some new tellurium containing dithiadiaza macrocyclic complexes of NiII, PdII and PtII have been synthesized via template condensation of 2-aminoethanthiol and diaryltellurium dichlorides, R2TeCl2 (R = p-hydroxyphenyl and 3-methyl-4-hydroxyphenyl) in presence of divalent metal chlorides. On the basis of elemental analyses, magnetic moment measurement, 1HNMR, Infrared and electronic absorption spectroscopy their structures have been elucidated. Based on these studies a distorted octahedral geometry to NiII complexes while a square planar geometry to PdII and PtII complexes have been assigned with the macrocycles coordinating through two S and two N atoms. These metal complexes have also been screened for their antimicrobial activity against some bacteria and fungi.
