摘要
Interaction of Re(NBu(t))3(NHBu(t)) and CF3SO3H in Et2O leads to the known [Re(NBu(t))3(NH2Bu(t))]O3SCF3 but also to a low yield, presumably via a competitive reaction, of a red compound, Re4(NBu(t))8(mu-O)2(mu-3-O)2(OSO2CF3)4, whose X-ray crystal structure has been determined. The structure has a Re4O4 core comprising oxo-bridged, five- and six-coordinate rhenium centres. The six-coordinate rhenium centres have cis oriented oxo, NBu(t) and eta-1-O3SCF3 ligands; the five-coordinate centres have pairs of NBu(t) and mu-3-O ligands and a mu-O ligand.
