Description
Summary:First isolation of air stable novel mercury tellurolate has been achieved using a ligand containing both steric and intramolecular coordinating features. Synthesis and characterization of stable monomeric mercury selenolate ( 9) and the novel air stable mercury tellurolate ( 10) incorporating [2-[1-(3,5 dimethylphenyl)-2-naphthyl]-4,5-dihydro-4,4-dimethyloxazole], containing both sterically more demanding and intramolecularly coordinating groups have been described here. These complexes were prepared in good yields by oxidative addition of mercury metal to the corresponding dichalcogenides in methanol. FT-IR, multinuclear ( IH, 13C, 77Se and 125Te) NMR, thermal analysis and mass spectrometric techniques were used to characterize these complexes. The complex 9 was structurally characterized by single-crystal X-ray diffraction analysis.
