Synthesis and Characterization of Ethylenediamine Complexes of Some Aryltellurium Trihalides

K. K. Verma, Seema and Shashi Chhabra

The synthesis and structural features of some newly synthesized ethylenediamine complexes of aryltellurium trihalides, RTeX3. EN (R = phenyl, p-anisyl, p-hydroxyphenyl and 3-methyl-4- hydroxyphenyl; X = Cl, Br, I) are reported. The complexes have been subjected to elemental analyses, conductance measurements, molecular weight determination, infrared and proton nuclear magnetic resonance spectral studies. Solution studies reveal their non - electrolyte or weak-electrolyte type behaviour. Spectral studies indicate the linkage of bidentate ethylenediamine molecule to the tellurium atom through the nitrogen atoms; thus, making it hexacoordinated.
