Abstract: | d,h-m?-Alkoxoalkylphosphonato-e-m?-alkoxo-f-m?-oxo-bistrichloroantimony(V)] Compounds The binuclear antimony(V) complexes Cl3Sb(O)R3(R1O)PO2](OR2)SbCl3 1 to 7 with R1, R2 and R3 = Me or Et in solution slowly exchanges the R2 groups between the equatorial oxygen atoms of the Sb2O2 ring. The SbO(3)PO(3)Sb ringsystem makes rapid pseudorotation. The resulting isomeres are detected by nmr spectroscopy. |
