Resumen:
The reaction of benzylferrocenyldithiophosphonate ligands [NH4][S2P(OR)(Fc)] [R = Bz (1), 4-(iPr)-Bz (2), 4-(tBu)-Bz (3), 4-(Ph)-Bz (4), 3-(OBz)-Bz (5); Bz = benzyl, Fc = ferrocenyl] with organotellurium iodides, C4H8TeI2 and C8H8TeI2, yielded the corresponding tellurium(IV) dithiophosphonate complexes [C4H8Te{S2P(OR)(Fc)}2] [R = Bz (6), 4-(iPr)-Bz (7), 4-(tBu)-Bz (8), 4-(Ph)-Bz (9), 3-(OBz)-Bz (10)] and [C8H8Te{S2P(OR)(Fc)}2] [R = Bz (11), 4-(iPr)-Bz (12), 4-(tBu)-Bz (13), 4-(Ph)-Bz (14), 3-(OBz)-Bz (15)]. Compounds 6-15 were characterized by elemental analyses, infrared, 1H, 13C, 31P and 125Te NMR spectroscopy and EI mass spectrometry, while complexes 6, 11 and 14 were also characterized by single-crystal X-ray diffraction studies. The dithiophosphonate ligands display an anisobidentate coordination mode upon interaction with the metal center. The solid-state structures show ferrocenyl groups in the dithiophosphonate ligands adopting trans arrangements. © 2014 Elsevier B.V.
