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.
