| Abstract: | Summary The complex Bu

N]Mo2O2Cl5(SPh)2] has been prepared by reaction of Bu

N]MoO(SPh)4] with stoichiometric amounts of HCl and characterised by single crystal X-ray structure analysis. The dimer is bridged by two oxo-groups and one chloride and each Mo has pseudo-octahedral co-ordination. The related compound Mo2O3(SPh)2(S2CNMe2)2] was synthesised by reaction of MoO2(S2CNMe2)2] with thiophenol in methanol and has also been characterised crystallographically. In this case the triple-bridge consists of two thiophenolate sulphurs and one oxo-group, each molybdenum having pseudo-octahedral geometry. These structures are compared with other triply-bridged species. |
