摘要:
The crystal structure of the molybdenum half sandwich alkali salt [Li(TMEDA)(2)][Mo(eta(5)-C5H5)(CO)(3)] shows the occurrence of a separated ion pair in the solid state. Furthermore, the crystal structures of the long known organotin complexes [Mo(eta(5)-C5H5)(SnMe3)(CO)(3)], [{Mo(eta(5)-C5H5)(CO)(3)}(2)SnMe2] and [Mo(eta(5)-C5H5)(SnMeCl2)(CO)(3)] have been recorded. The chlorination of [Mo(eta(5)-C5H5)(SnMe3)(CO)(3)] with SnCl4 is presented as an improved synthetic access to [Mo(eta(5)-C5H5)(SnMeCl2)(CO)(3)]. Finally, the reaction of Li[Mo(eta(5)-C5H5)(CO)(3)]with Bu-t(2)(Cl)Sn-Sn(Cl)Bu-t(2) leads to the novel molybdenum distannane complex [Mo(eta(5)-C5H5){(SnBu2)-Bu-t-Sn(Cl)Bu-t(2)}(CO)(3)], which is fully characterized by NMR, elemental and X-ray analysis.
