UNSYMMETRICAL DITELLURIDES AS LIGANDS: REACTIONS WITH COPPER(I) AND MERCURY(II) HALIDES

Article abstract of DOI:10.1016/S0022-328X(00)85719-8

Reactions between copper(I) halides or mercury(II) halides and equimolar mixtures of diphenylditelluride (R2Te2) and bis(p-ethoxyphenylditelluride (R'2Te2) give materials of stoichiometry (M=Cu, X=Cl, Br, n=1; M=Hg, X=Cl, Br, n=2).Change of solvent from propionitrile to ethanol gives <(RTe)(R'Te)Hg2Cl2>m.Mass spectroscopic data and Raman spectra are presented and discussed in terms of the probability that the unsymmetrical ditelluride is present as a ligand. ν(TeTe) for PhTeTe(C6H4OEt-p) occurs at 170.5 cm^-1 in benzene solution.
