The compounds [TlR2(S2PEt2)] (R = Me or Ph) were synthesized by reaction of the corresponding hydroxide TlR2(OH) with NaS2PEt2·2H2O and characterized by X-ray crystallography. In both structures thallium is coordinated to the two sulfur atoms of the diethyldithiophosphinato ligand and to two carbon atoms of organyl groups. The chelate ring, TlS2P, lies on a crystallographic plane of symmetry. Weak intermolecular interactions with one of the sulfur atoms of a neighbouring molecule make the coordination number of the thallium atom up to five. The vibrational and 1H, 13C, 31P and 205Tl NMR spectra of these compounds are also discussed.
