Solution spectra of diethyldithiocarbamate complexes of tellurium(II) and (IV), Te(dtc) 2 and Te(dtc) 4, have been recorded.Spectral evidence suggests that both the dtc ligands of Te(dtc) 2 are unidentate, and that two of the dtc ligands of Te(dtc) 4 are unidentate, and the other two bidentate. Thus tellurium in Te(dtc) 4 is in a distorted …
