摘要：
When RhCl3 center dot 3H(2)O was treated with an excess of Te(CH2SiMe3)(2), a mononuclear mer-[RhCl3{Te(CH2SiMe3)(2)}(3)] (1) was observed as the main product. By reducing the metal-to-ligand molar ratio, dinuclear [Rh-2(mu-Cl)(2)Cl-4{Te(CH2SiMe3)(2)}(4)] (2) was obtained in addition to 1. Further reduction of the metal-to-ligand ratio resulted in the formation of [Rh-2(mu-Cl)(2)Cl-4(OHCH2CH3){Te(CH2SiMe3)(2)}(3)] (3). The treatment of mer-[RhCl3(SMePh)(3)] (4) with two equivalents of Te(CH2SiMe3)(2) affords a mixture of mer[RhCl3{Te(CH2SiMe3)(2)}(3)] (1) and mer-[RhCl3{Te(CH2SiMe3)(2)}(2)(SMePh)] (5). All complexes 1-4 and 5 center dot 1/2EtOH were characterized by X-ray crystallography and Te-125 NMR spectroscopy, where appropriate. The definite assignment of the Te-125 chemical shifts enabled a plausible discussion of the assignment of some unknown resonances that were observed in the NMR spectra. (c) 2009 Elsevier B.V.
