A novel heterobimetallic W-Ge compound. X-ray crystal structure of [W(mu-Cl)(GeCl_3)(CO)_3(eta~4-C_7H_8)]

摘要

The new heterobimetallic complex [W(mu-Cl)(GeCl_3)(CO)_3(eta~4-C_7H_8)] (1) has been prepared by photochemical reaction of W(CO)_6 with bicyclo[2.2.1]hepta-2,5-diene ( NBD) and GeCl_4. The structure of compound 1 was established by X-ray crystallography. The IR, ~1H and ~13C NMR spectra are also described and correlated with the crystallographically observed geometry Compound 1 is noteworthy since it is the first alkene complex of tungsten isolated in W(CO)_6-Lewis acid photocatalytic system.
