Abstract
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 Mo 3Te3S4+ 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 cryst allographic analysis revealed that these complexes belong to the Mo3E44+ (E = S, Se, Te) incomplete cuboidal cluster family and are dimeric through th e Te ... Te interaction. H-1 and P-31 NMR and IR spectroscopic data were al so used to characterize these compounds. (C) 2000 Elsevier Science Ltd All rights reserved.
