Twenty new complexes of hydroxyaryltellurium trichlorides derived from isomeric cresols and ortho-chlorophenol with pyridine (Py), 2,2′-bipyridyl (Bipy) and piperidine (Pip) have been synthesized and characterized by elemental analyses, conductance, cryoscopy, infrared and proton magnetic resonance studies. Pyridine and piperidine form RTeCl3.L and RTeCl3.2L complexes, whereas 2,2′-bipyridyl which acts as a bidentate ligand and gives only RTeCl3.L complexes. Conductance and cryoscopic measurements reflect their weak or 1:1 electrolytic behaviour in solution of nitrobenzene, acetonitrile and acetone. Spectral studies indicate the linkage of these ligand molecules to the tellurium atom of the hydroxyaryltellurium group through nitrogen atoms. A square-pyramidal structure is suggested for RTeCl3.Py and RTeCl3.Pip, whereas 1:2 complexes of pyridine and piperidine along with RTeCl3.Bipy, have octahedral stereochemistry.
