Abstract
The two compounds, trans-Cp2Mo2O2(mu-O)(mu-Te) and cis-Cp2Mo2O2(mu-O)( mu-S), were isolated in 31% and 36% yields respectively, when a benzen e solution of Cp2Mo2Fe2(CO)(7)(mu(3)-S)(mu(3)-Te) was refluxed for 3 h in the presence of air. Characterisation was carried out by IR, H-1 N MR and Te-125 NMR spectroscopy. The structures, established by single crystal X-ray diffraction analysis, consist of an ore-bridged dimolybd enum unit containing a mu(2)-Te atom in one case and a mu(2)-S atom in the other. Also attached to each Mo atom are a Cp ligand and a termin ally bonded oxo group. (C) 1997 Elsevier Science S.A.
