文摘

The reaction of tributylphosphine, benzoic acid and Mo₃Te₇(S₂P(OPrⁱ)₂)₃I produced a new compound with triangular cluster skeleton Mo₃Te₄⁴⁺, Mo₃Te₄[S₂P(OPrⁱ)₂]₃(μ-PhCO₂)PBu₃ (1). An unexpected compound including an Mo₃Te₃S⁴⁺ skeleton, Mo₃(μ₃-S)Te₃[S₂P(OPrⁱ)₂]₃(μ-PhNH₂CO₂)PBu₃ (2), was obtained using aminobenzoic acid instead of benzoic acid. X-ray crystallographic analysis revealed that these complexes belong to the Mo₃E₄⁴⁺ (E=S, Se, Te) incomplete cuboidal cluster family and are dimeric through the TeTe interaction. ¹H and ³¹P NMR and IR spectroscopic data were also used to characterize these compounds.
