Syntheses and structures of two complexes with incomplete cuboidal Mo3Te44+ and Mo3(μ3-S)Te34+cluster cores
摘要:
The reaction of tributylphosphine, benzoic acid and Mo3Te7(S2P(OPri)(2))(3)I produced a new compound with triangular cluster skeleton Mo3Te44+, Mo3Te4[S2P(OPri)(2)](3)(mu-PhCO2)PBu3 (1). An unexpected compound including an Mo3Te3S4+ skeleton, Mo-3(mu(3)-S)Te-3- [S2P(OPri)(2)](3)(mu-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 Te ... Te interaction. H-1 and P-31 NMR and IR spectroscopic data were also used to characterize these compounds. (C) 2000 Elsevier Science Ltd All rights reserved.
