Twelve new salicylhydroxamate complexes of the type ArTeCl2.SHA, ArTeCl.(SHA) 2, Ar2TeCl.SHA and Ar2Te.(SHA) 2 (where Ar = p-methoxyphenyl, p-hydroxyphenyl, 3-methyl-4-hydroxyphenyl; SHA = salicylhydroxamate) have been synthesized by reactions of aryltellurium(IV) trichlorides and diaryltellurium(IV) dichlorides with potassium salicylhydroxamate. The aryltellurium(IV) hydroxamates have been characterized on the basis of elemental analyses, conductance measurements in DMSO, infrared and proton magnetic resonance studies. The spectral studies conjointly predicts the bidentate (O, O′) nature of hydroxamates to yield the penta and hexa- coordinated tellurium complexes. The biological activities of these complexes were evaluated against some pathogenic bacteria and fungi organisms.
