Abstract
2-(Aryltelluro)ethylmethylsulfide (1), where aryl = 4-MeOC6H4 (a) and 4-EtOC6H4 (b), has been synthesized by reacting sodium aryltellurolate with CICH2CH2SCH3. 1H and 13C NMR spectra indicate the existence of intramolecular Te←S secondary interactions in 1. IR spectra suggest that both the trans and gauche conformations of two CH2 groups coexist, at least in the solid state. (C6H5CN)2PdCl2 and K4PtCl4 react with 1 to give diamagnetic complexes of the type Pd/PtCl2.1. IR, 1Hand 13C NMR data in conjunction with molecular weight and conductivity measurements suggest that 1 in the complexes acts as a bidentate ligand and two CI (cis to each other), S and Te atoms constitute the square planar geometry around Pd/Pt, as supported by electronic spectra.Keywords
